oldtimer wrote:"no flip flops in trees" (good tree-climber wardrobe decision, too?); tailor your climbing __style__
Wait a minute I have seen pictures of Nick Climbing on Flip-flops and wearing colorfull pajama pants, So that recomendation on keeping with tailor "_style_" is out of the question! 
Hey Nick, help me here. Where is your photo climbing on Flip flops, wearing pajamas and wearing a dust mask on a tree near the road in a park in CA? Inquiring minds want to see it again to show what climbing in _style_ is all about. 
I'm hoping that someone (Nick) will run an "alternate footwear only" climb at the next rendezvous. There would be qualified medical personnel on hand to treat stubbed toes.
