Hmm, I know Jim fairly well, and I'm thinking he's being a bit sarcastic here, so take it for what that's worth.

There's light and then there's stupid or perhaps ignorant (and there is a difference).

As far as the PS fatalities, I remember getting out of my car at 8 in the morning in July after driving out to Indio and it was about 90F already. No way I'd be out hiking in those temps.
