I'll be visiting the US in late February through to mid-March. This is primarily to talk at the Council for Secular Humanism conference in Orlando at the beginning of March. But I do have some other gigs arranged - in Hartford, New Haven, and Buffalo (CFI headquarters in Amherst).
Unfortunately, time will preclude any others. Hopefully there will be another chance at some stage, and I may be able to stay longer next time. Unfortunately, I don't have the sort of financial resources to do this sort of thing out of my own pocket (thanks, in this case, to the CFI/CSH for covering my expenses relating to their gigs, which includes actually getting me to the US and back).
I'll announce details a bit closer to the time for people who live in those areas or are thinking of going to the Council for Secular Humanism conference.
