One of my few complaints about Gen Con is that it normally hits the same days at the World's Longest Yard Sale. Last year the days were off but normally they are both on the same weekend. I'd recommend this as a nice drive and some good outdoor exercise:

This is a fascinating event that I never would have guessed existed, and that I feel enlightened to have learned about! Thanks Qwaserity!
Secondary silver lining for the (NOT) GenCon weekend. Lindsey Sterling is playing in Cincinnati the weekend GenCon was supposed to happen. https://www.ticketmaster.com/linds.../event/1600585AA76C5FFD
