It sounds like the parking lots outside of the Fort Washington Expo Center will not close, so this will allow people to camp out there and have BBQs and such. I am finding out more about this, so I can see what I can bring, but sounds pretty cool if it is correct.
Also, when registering myself I found out by this Friday you can still get the discounted price of $50, after this Friday, I think it goes up to $75 (thought I try and save people some money).
