Well, the one big thing I was worried about has come to pass....
It appears the bridge over currie road is not going to be complete by Pennsic. Not the end of the world, but certainly a pain in the <insert your expletive of choice here>.
Anyway, what that means to you is that you need alternate directions for when you come out to site. I strongly recommed you use the ones supplied by www.cooperslake.com. If you use those then you'll get there in one piece no matter your trailer or vehicle size. Google Maps may send you down a railroad bed or down back roads that are effectively one lane wide.
For those of you worried about details, we've adjusted all our plans. EMS has thier alternate routes planned and our other contingency planning has been updated, so we're still good to go.
Hopefully very few of you will get lost, and if you have a large vehicle or trailer I strongly encourage you to use the directions on the website (In fact I encourage everyone to use those directions).
