I just got back from the Arizona Winter School, which this year was in fact held in Arizona, specifically at the University of Arizona in Tucson. It was one of the more intense math experiences I've had -- we were up working past midnight every night, including until 4.30 am preparing our presentation on the last night.

I was not impressed with Tucson. Everything is huge and spread out -- as my friend Tony observed, even the small side streets are 8 lanes wide. And I didn't have a decent meal the whole time I was there. However, I was very impressed by the cacti. I'd never been anywhere where cacti just grow on the side of the road, some of them as big as ordinary trees.

All in all, I'd rather visit New Mexico.
