Well I just voted for Alexandria, VA after taking a couple days to think about it!
I'm sure if we did a breakdown in the votes, most people voted for cities closer to their homes for various, common sense reasons, travel, financial, etc..
I think it's common sense to also expect that whichever coast wins out, the majority of people from the other coast will probably not attend. I think that is just reality and whoever that may be, we will just have to bide our time until the next year when it makes it's way across country!
The US seems to be pretty darn big when you are trying to gather people from one end to the other to meet in one place!
