Oh my, where is that strawman, again. I did build up something that wasn't pertinent only to knock it down. I said there are canister requirements at Whitney, Rae Lakes and Yosemite. True statements. I was told at many places by those who should know the rules that if you pass through area you need a canister. True statements. If he went without a canister based on the latter statements he was in violation of the law.
Me thinks, you should learn what a strawman argument is.
Again, I will say for the at least the 3rd time this was a heck of feat.
