A group of volunteer fire fighters from Waterloo helping victims of Tropical Storm Harvey met J.J. Watt at a receiving station over the weekend.
The men traveled to the Houston area to help people displaced by widespread and historic flooding in Texas.
Watt, who's Harvey relief fund hit $20 million in donations Tuesday, was at the receiving station for a live shot with ESPN. The Houston Texans defensive end took a moment to take a picture with Mike Frost, Josiah Black and the rest of their group.
"We were loading up our truck and he just showed up," Black said.
Black and Frost say the trip has been a once-in-a-lifetime experience.
"Its amazing to see how they lost everything but they're just so positive down here," Black said. "That's almost like all they can do is hope for the best."
