All the news is abuzz with the warnings about parking being real crowded for opening weekend. They're telling people to park at Lakewood or to take Marta. I have a handy Turner Field Guide that details some useful tips about the ballpark as well as directions to where I like to park, though it's probably going to be really busy over there too. So, get there early, early, early.
Along the lines of parking, I found this mini-documentary about the "gypsy" parking lot folks that used to be all around Turner Field. I don't know that I would call the people currently there "gypsies," but this is some interesting footage - a bit long, but interesting.
