Thanks for the replies guys, I haven't posted but I've been checking back here every so often.
I was at one of the houses yesterday and it was a blast. The guys all introduced themselves, gave me a tour, we played some poker, and then they insisted on giving me a ride home. They were all really chill and cool. Although I'm planning to look at a couple of other fraternities as well, I really liked hanging out with these guys, and they said we'll probably do something again on the weekend, so I'm looking forward to checking that out.
If you guys still have any tips or any houses I should check out, let me know!
Hope you all had happy holidays!
