Visiting Waipio?

[oink]

I've walked down it and back up (not 50 times) in slippers/sories/flipflops. It was a fair workout but nothing more. It would have been more challenging if raining. Walking accross the river with all of the round rocks was tough in the slippers. My knees are crap now so a repeat isn't likely, although on a good knee day I might try it.
