I hope you have a safe trip around the country, and get time to enjoy some recreation along the way!
I don't know how attendance is, but if you could target smaller cities I think that would benefit people who never have an opportunity. Instead of Chicago, somewhere like Hammond, IN or Champaign, IL. Maybe Peoria or Springfield as well. I know you are limited in how many locations you can visit. Personally, I think a lot of people in these locations aren't able to travel due to cuts in spending. Shouldering the cost for a hotel yourself can be prohibitive in Chicago!
Of course if attendance is small, this suggestion might make it worse.
Either way, thanks for providing the opportunity.
