I rode up from LA through Vegas on my way to Miller Motorsports park for the SBK\ WSBK races. It was in June and I thought that was hot. Then I went up to Yosemite a few weeks ago (the 395 admittedly). I was pulling over every 75 miles just for water. Drinking gallons of it and not peeing. It was 120. My buddy who is an old crusty bastard on a big ole Soft Tail just went through Vegas on his way to Sturgis. He said it was the hottest he'd ever been. Doing it is bad, but in August it's just plain nasty. Worse, it's a really boring ride. And then being in Vegas and knowing you have to come back? No thanks. The Greek place in Baker has good Bakalava though - makes for a nice pit stop.
Personally I'd rent a limo, get the girlfriend and one of her hotter friends, liberal doses of Tequilla and create my own travelling Penthouse Forum moment. Jesus man, you're going to Vegas!
better lock this thread. there's nothing else to say.
