The heat hasn't really bothered me too much. I'm staying hydrated and my mesh gear has good ventilation, so as long as I'm moving, I'm good (and I miss lane splitting). And even though it was relatively cool for Phoenix at 100, I think that should be the hottest bit of this trip, so the hard part's over. Nevada might get close though.
I'd forgotten how pretty the clouds can be out here! I love seeing a sky full of puffy clouds, plus the sunset was breathtaking tonight.
