River surfing, he added, is different. “In the ocean, you wait and wait for the perfect wave and it’s great when you finally get one,” he said. “But here you just have to wait on the side until it’s your turn. In a way, it’s like riding a dirt bike off-road versus riding a motorcycle on a racetrack. River surfing is like a racetrack. The water is coming at you at high speed but it’s constant and the conditions are almost always the same.”
