Aside from watching Katie, Matt and newly slimmed-down Al drool over humongous balloons and high school bands with your own loving yet dysfunctional family, the best thing to do on Thanksgiving might be to hook up with the locals at The Cave in Chapel Hill for their 20th annual potluck. Bring a dish, set a spell, and commune with your neighbors. If you're particular about avoiding meals that involve animal flesh, check out the Triangle Vegetarian Society's Thanksgiving Dinner at Café Parizade in Durham from 1-4 p.m. It's an annual thrill for local veggies; if you've never been, it's time to wave your home Tofurkey goodbye and experience the vegetarian bounty. Call the Cave at 968-9308; read more about TVS' feast at http://www.trianglevegsociety.org/thanksgiving02.html and call 572-0093 for reservations.
