I'd play STAW organized but Columbia is a haul for me (I'm in Charleston SC). If it's actually organized and there are prizes and stuff that might make the trip worth it (rather than just 1 or 2 pick up games).
I'm in Charleston also we have been running the OP event with prizes at Realms fantasy games in Summerville, SC for the past few months, if you're interested in coming out we would love to add more people to the group. Our numbers have been a little low so the more the merrier. We typically run OPs for this on Wednesdays and as soon as Escott posts a day for Month 5 it will be up on Wizkidseventsystem.com and I'll put a post up in this forum.
