same here, i am quite a bit further from the park than Dave, (about an hour+) but if people need a free place to crash, i have 3 extra beds and a couple couches.
Yes, I believe the date is now pretty much set at Sept 2-4.
and yes thats fine if people want to crash here. my only request is that i know in advance who/when so that i know if i need to do anything as far as work schedule so people wont be sitting around outside my house for a couple hours
