Beloit is in a pretty good location for attending tournaments; you're within striking distance, Chicago, Urbana, and Ann Arbor (and, I might add, Minnesota). You'll want to hold a few practices on BARGE-level questions before you decide to attend that tournament, because it may be a bit tough for an introductory event. You should definitely attend NAQT's Division II SCT and Illinois's site of MUT/GAAP. Both of those tournaments will be happening in the spring and will be novice-friendly.
I would also suggest visiting http://collegiate.quizbowlpackets.com
and checking out the archives of ACF Fall. Reading through those packets will give you an idea of what introductory college tournaments look like. Start with the most recent packets and move backwards, because some of the earlier iterations of Fall are a little harder than today's versions. If you're looking for something similar to BARGE, check out the most recent versions of the Terrapin Invitational, which are of similar difficulty (and were edited by the writer of BARGE, Chris Ray).
