PUEBLO, Colo. – Brant Atwood and his fellow cowboys were cruising up and down the streets of Spring, Texas, hollering toward the houses that had water up to their second-story floors trying to find anyone that may be need of assistance.

Atwood, with a black heavy duty garbage bag wrapped around his recently casted broken arm, then began to hear barking and whining coming from behind one of the houses.

The 30-year-old bull rider from Pampa, Texas, eventually pulled the boat toward the back of a house where he discovered two dogs struggling to stay alive amidst rising flood waters from Hurricane Harvey.

Atwood and his buddies broke down a fence and quickly got the two dogs unchained and into their boat.

“There was probably 24 inches of water in the backyard,” Atwood said Tuesday night. “They were close to drowning. You could see their necks were just rubbed raw from trying to get out of their collars and break free.”

Atwood has been in the Houston area since early Tuesday morning working alongside Dale Fultz, Cody Brown, Chris Marquez and Zarni Win to help local authorities with on-going relief efforts following the catastrophic and deadly hurricane.

Atwood had only gotten his left arm casted on Monday after sustaining the injury at the Real Time Pain Relief Velocity Tour event in Salinas, California, on Saturday night.

There was no doubt that Atwood wasn’t going to let his injury get in the way of heading down to Houston this week.

“I talked to Bryan Titman (East Bernard, Texas), Neil Holmes (Houston) and all those guys. I had seen how bad it was and people’s homes,” Atwood said. “I knew I had a couple of buddies coming down here. I had to doctor out for the next few weeks, so I can’t really day work, and I might as well come down here, enjoy the excitement and get to help people out.

“It makes you feel good on your off time.”

Atwood and his wife, Kaci, as well as the other North Texas volunteers, brought a slew of donated items to the Gulf Coast. The Atwoods organized a truck-bed load worth of bottled water, diapers, baby wipes, blankets, clothes, dog food and cat food.

Fultz and Smith also hauled a couple thousand dollars’ worth of donations from the Fort Worth, Texas, area.

Atwood said the group water-rescued “roughly 20 people” on Tuesday, as well as the two dogs and an armadillo from a tree, by working alongside fire marshals in the region.

“We have been wrangling; but we were wrangling humans, not cattle,” Atwood said.

The group spent almost two hours trying to maneuver their way around debris to reach one distressed family of 10 people. Once they got to the family, Atwood said a new problem emerged.

The biggest obstacle was people not wanting to leave their homes because of all of the looting,” Atwood said. “We would find people and they wouldn’t want to leave their homes because everyone was stealing their stuff.”

The crew of North Texas volunteers was back in the water at sunrise on Wednesday morning in Kingwood, Texas, -- a 14,000-acre community in northeast Houston.

“There is supposed to be a lot of people being transferred back and forth today,” Atwood said. “Fire marshals are setting up checkpoints at all the fire houses. You go there and they send you out to wherever they are getting emergency calls. Since we have three boats, they will send us as a group to go get 10-15 people at a time.”

2009 PBR Ring of Honor inductee and stock contractor J.W. Hart left at 4 a.m. Wednesday morning to help join relief efforts in south Texas too, while PBR in-arena announcer Clint Adkins continues to volunteer his time and pontoon boat.

Titman has been volunteering in East Bernard and Wharton alongside the U.S. Customs and Border Patrol.

He also helped move cattle and livestock through treacherous waters on Saturday.

On Wednesday, Titman helped get a woman and four kids off the roof of a barn that they had been trapped on for a day.

“It’s sad,” Titman said. “Everyone is pretty bad off. A bunch of businesses lost roofs too. This whole thing is pretty sickening.”

Titman had hoped to unite with Atwood but there has been too much damage and flooding between the two.

The 29-year-old bull rider also was unable to make it across town to help assist members of his family.

“My aunt and uncle they were stuck on their roof and they finally got a boat to come rescue them,” he said. “My mother’s house had a roof fell through.”

Millions of people have been displaced and affected by the now Tropical storm, which has dumped nearly 52 inches of rain on the country’s fourth-largest city.

According to the private weather firm AccuWeather, Hurricane Harvey could be the costliest natural disaster in U.S. history. The $160 billion price tag will be equal to the combined cost of Hurricanes Katrina and Sandy.

One of the boats Atwood is using is actually the same boat that he won at the 2013 PBR Built Ford Tough World Finals when he won the annual Bass Pro Shops’ rider raffle.

The Whitesboro, Texas, resident had maybe used his boat a dozen of times before this week’s relief mission.

“I figure God provided me with that boat for a reason and I haven’t used it maybe a dozen times,” Atwood said. “It is pretty crazy. I figure I am hurt and I can’t day work and God provided me with a boat. I am going to go down there and help out with all of these guys.”
