Easy Rider

I thought the scene at the beginning of the movie when Wyatt discards his wrist watch helps to illustrate the attitude or spirit of their road trip (rebellious, carefree). And then later Wyatt says to the rancher, "You do your own thing in your own time. You should be proud." I think this is what Wyatt and Billy are searching for on their road trip, personal freedom. They are doing their own thing on their own time, free from time constraints and social conventions.

Question: What did Captain America mean when he said, "We blew it."?
