Port City is a great group of guys. They have a facebook page, couple of their members are on here I believe. If you want a more serious magfed/tactical group, look up Callsign Boxer. Another good group of guys who, from my dealings at least, a bit more into the tactical style of play.
As a side note, there's a 1 day scenario on 5/18 at ABP. There's usually at least a couple guys from Port City at those games.
For trade: Super clean skinned lime DM15, matching rotor available as well for the right deal. Pics here:
Bellauwood Bruisers is a magfed team from Jax, they were last playing at Adrenaline Junkie in Leland. I think they may have something for magfed there. not sure about Southwest or NOTG. Boxer is pretty far west but I would think he may be able to point you in the right direction.
Chrono301 no longer has any magfed on the team, but you are welcome to play with us when we travel to a game.
