Someone paid a fortune for the “Captain America” Harley-Davidson supposedly used in the 1969 counterculture movie’s final crash scene. Former Grizzly Adams star Dan Haggerty had restored — and authenticated — two different bikes used in the film. He insists the one sold this weekend was the one from star Peter Fonda’s death scene. The owner of the other bike disputes that. “There’s a big stinking rat someplace in this,” said Fonda, who had signed both bikes. But the anonymous buyer clearly didn’t mind the stench.
