WESU is having their bi-annual record fair on Sunday. It's free admission and I've personally found some great things there in the past. I'm looking forward to digging for more. The past couple times they've had food trucks outside too. And hell, it's a nice enough campus to walk around (if it's not raining - which I fear it very well might). Good Sunday afternoon activity; it's going from 11AM-4PM. Directions here.
