Where was the original cosplay picnic supposed to be? You'd think there'd be a spot nearby that could be used... I certainly would want to stay close if I were attending, seeing as how
a) costumes can be finicky to have to drive long distances in and
b) gas prices are ridiculous right now and
c) personally, I don't know the area at all, so I'd rather not have to go back and forth all over God's Green Earth, thus multiplying my chances of getting lost.
