There are a lot of watering holes in Tucson. I think the number of bars in a given location increases with the amount of Mexican food available. Hot and beer go well together. As does young and beer.
With the University, there are a lot of Olsen-esque girls around, and now's a particularly good time to go fishin' for 'em: finals are coming up in a little over a week, so student's are stressed and vulnerable, open to guidance from an experienced hand.
That said, I think I will watch LA's twitter to see if he announces a ride. I'm not an LA fanboy for his riding (nor am I hater for that reason), but I am a tremendous fan of what he's done for cancer patients. Plus if I can get him to sign my Look 595, I can sell it on eBay for 7 times its value. Plus, I think he's been good for the bike scene in the US. If he could only use his powers to rid us of the hipster/fixie plague and cure recumbent riders, the world would be two steps closer to being perfect.
