The lot in Fredericksburg is the spot on the weekends during the summer time. I havent been out there latley but some of my friends were there last Saturday(15th) and they said it was pretty packed, its organized by the local police but theyre never out there patrolling. I think theres a few cops out there but theyre not in uniform.
I havent been to Mannassas since the this summer, it was aight last time I was there, I guess when its cold noone comes out anymore??
But if you guys havent been to Fredericksburg you should check it out. If its not raining or freezing cold, there should be a good amount of people out there, around 10:30 is when the majority of the people are out there.
