BALTIMORE, MD (WKBW) - It happened in the final moments of his 300 foot walk above Baltimore's Inner Harbor.

Daredevil Nik Wallenda's foot slipped of the tightrope. He caught himself using his shin. What went wrong? Wallenda said he let his guard down.

"I get comfortable cause I'm almost done and I looked up and was talking to a friend of mine that was in the basket and I slipped and he turned pale white and freaked out," Wallenda said after he completed the walk.

"I'm okay. So that's what matters," he added.

The stunt, to celebrate the opening of a Baltimore museum, was a recreation of his great-grandfather's walk above Baltimore in 1973.

The cable was connected to the museum at one end and a barge floating in the water on the other.

"No one in the world has ever been hooked to a moving object like that so there'll be a little more movement in the cable. Other than that it's a fairly normal walk," said Wallenda.

It is a walk in the park compared to Wallenda's next stunt. On June 15, he will walk nearly three times the distance over the Canadian Horseshoe Falls.

Wallenda will practice the walk from May 12-22 in a parking lot at the Seneca Niagara Casino. There will be two practice sessions a day at 10:30 and 3:30. Both sessions are open to the public.
