Well, you do need to get a membership for the con, though actually you might like to come to a housefilk some month? That's basically just a gathering at someone's house to talk, make music, and have fun. The next one is in April, and you'd both be welcome. As for the con, detailed information is here:

Membership prices vary by how early you get them, and if you want to get the whole weekend or just one day. Email me, or if you want mention it Friday when I bring by my sheet. :)
