I stayed a couple days to attend some of the sessions and learned a lot of interesting things about better diabetes treatment and upcoming research. (No we really are not that close to a cure...it's way more complicated than you think).
I took a few hrs to do a little sightseeing: shopping on the Magnificent Mile, a riverboat tour about the interesting architecture but it's really not as fun when you travel by yourself. I got a good feel for all the crazy traffic there riding shuttles to/from airport and to/from the conference each day-I soon learned to bury myself in my book rather than watch out the window...that is, unless you had to sit in the front seat with a very talkative shuttle driver that wouldn't let you. It is fun city right downtown and the building are very interesting.
