Yeah, I probably wouldn't go for the naturalist thing. I mean, there are some really specific situations where that would be fun I suppose, but not this particular occasion. I read a story not too long ago about a naturalist club, I think in the Flatirons in Colorado, that does nude climbing of some of those routes. I'd find and link the article but I'm currently at work so, when the rudimentary Google search for "naturalist rock climbing Colorado" came up negative, I figured it would be best to not really start pushing limits with search keywords.
So, back to the business at hand, Costanoan or otherwise, would anyone be interested in any late evening/nighttime climbing between now and about September 15?
