[cfm] You were in Boston last week?? I was there (well, technically, Cambridge) for a conference. (And yes, it was definitely hot, though I spent most of my time in airconditioned meeting rooms.)
Just back from a wedding in Chamonix. Even at that elevation, it was still 30°C and over. On the plus side, the weather was beautiful and the reception lavish. Go to a French wedding, if you're asked. You will not regret it.
