Okay, just a bit of info for peops going to Siege...
If you can get to a MARTA Station there's a high chance you can get to Siege. The closest station to the Siege venue that I could find is Sandy Springs (Red/Yellow Line). However, Sandy Springs doesn't have any connecting bus routes to get to the venue. So your best bet is to get someone to pick you up at the Sandy Springs MARTA station (like 10-12 mins from the venue) OR...
You can go to doubles in the morning at Flea's place which is accessible by MARTA (almost...). Flea's place is closest to the Decatur MARTA Station (Blue/Green Line). There is a connecting bus route, the 123 N. DeKalb Mall/Belvedere Bus Route. Get off at the first stop aka the Dekalb Medical-North Decatur Center area and either get someone to pick you up or print out walking directions for yourself.
It's a 2 min drive from the bus stop to Flea's place or a 12 minute walk. The following addresses are what you can put into Google Maps in order to get directions however you wish. Once you get to Flea's you can hitch a ride to the venue most likely but you need to make sure you have a ride before hand.
Flea's Address:
455 Dekalb Industrial Way, Decatur, GA
Bus Stop Address:
Rufus Evans Dr@Sycamore Dr @33.790413,-84.285264
Decatur MARTA Station Address:
400 Church Street, Decatur, GA
Sandy Spring's MARTA Station Address:
1101 Mount Vernon Highway, Atlanta, GA
Venue's Address:
6345 Powers Ferry Road, Atlanta, GA
I suggest leaving AT LEAST 2 hours early since MARTA is reliable but not a very fast way to travel (especially if you have to wait on the train and/or people to pick you up from the stop). Try not to get DQed people.
Hopefully this may have helped someone... at the very least it's helping me get there
good luck everyone and I'll see you at Siege.
