A mathematical tour of the US

I would like to visit all 50 US states; my tally is currently at 48. Some colleagues have pointed out that a visit to a state shouldn't really count unless it involves a talk; so I'm also working towards giving a mathematical talk in all 50 states. For this goal, my tally stands at 31 (plus DC). Listed here is a talk in each state.

Sebi Cioba is also keeping track of states where he has talked.
