Consider what it does to the senses when you're in a kayak on the Colorado River and you hit white water. You can't hear anything but the water. There's spray in your face. Violent drops. Wicked turns. And fear -- moments when the river seems to be in control, not you. In short, it's total sensory overload, a total adrenaline rush.
"It's got to be visceral," said Doug Gilstrap, 47, who has run the camp since it launched in 2001. "It's stimulating, it's super-intense. And, actually, the more intense it is, the better they are on the other end."
It's about taking kids to the extreme, the kids who have difficulties with extremes in everyday life, he said.
"Many times our kids, campers have a lot of behavior issues or a lot of sensory issues that they just can't handle," Gilstrap said. "It's too cold, it's too hot, it's too bright. All those sorts of things can cause a lot of problems."

The kids here, ages 5 and up, represent the many different ways autism can take shape. Quinn, like several kids at the week-long camp, barely speaks, while Johnny talks and talks. The girls are more physically timid than most of the boys, while a few kids, like Josh, are athletically gifted.
One of Josh's challenges was to take on a steep rock wall.
"So, with any person, a new thing can bring about some fear and some apprehension," Gilstrap said. "It's even heightened with autism. A situation that forces focus, like here, knowing where to put your feet, figuring out what piece of rock to grab onto -- you can see Josh working it through, 50 feet up, and then the rappel back down.
"We've built the camp around, sort of, not to use the word 'extreme,' like 'extreme games,'" Gilstrap said. "It's extreme in the sense that all the activities are visceral."
Back on the ground, Josh was asked if it was a hard ascent.
"It was hard, yes," he said, adding that he found all the cracks he needed.
"The greater the adrenaline shock that I can put to the system -- the brain, the body and the endorphin rush that comes in post-adrenaline rush -- is what gets them the most relaxation and calm," Gilstrap said. "When they are back in a normal situation, they have better capacity to be in control."
Internal struggle is visible on many of the campers' faces, as they move over ropes high above the ground.
The Extreme Sports Camp features ropes that go over a river and back again, and then run up to tree level. While every kid is in a safety harness -- they can't fall to the ground -- the kids can still slip off the line as they try to cross it, and do.
"Some kids need a little more pushing and some need a little less," Gilstrap said. "If the kid doesn't need pushing, I don't come and push -- I just let them do their own thing."
Gilstrap tried to coax a camper named Johnny to try the ropes.
"You go first," Johnny said.
"Are you scared?" Gilstrap said. "That's the way you learn from it."
Johnny moved tentatively along a rope.
