He actually decided on Coconino Loop, rather than the 300. Good choice with the temps. Still a big gear, though...
Probably a good choice a couple of weeks ago it was still quite hot, temps are coming down though. We went 24 hours with out running the cooler just a couple of days ago, only running a couple of hours a day now. Highs for this weekend 95 however just a couple of weeks ago a guy had to be rescued off of the north end of the Catalina's
