my chapter is really close with our surrounding chapters. when my chapter chartered last year, our Northern Arizona and San Diego chapters came to watch. it was really nice having everyone all together, like a family reunion. Just the other day me and a brother were traveling to San Francisco from ASU and we stopped over at the San Diego house and participated in their philanthropy. its real nice having other chapters close by. i really want to check out some of the DU houses over on the east coast where DU is really big. i saw pictures of the Indiana house and it is ginormous.

I am drooling overthat one... the BALCONY!

ETA: 4000th post :D

I have stayed at the DG house at Mizzou since we used to do our last Rush School there before our Formal Rush (they start later in January than we do). I know my chapter uses the DG house at Illinois now, but I haven't seen that (despite being from IL). I've also been at the DG lodge at Colorado College.
I have seen the outside of the DG house at Michigan, but didn't go in.

In terms of other chapters, I've stayed at the Sigma Kappa house at Michigan (it's gorgeous!). I was also in the AXO house at Northwestern a lot in high school because my math tutor lived in the house.

I was in most of the fraternity houses on my school's campus in undergrad, but I've also been in the Kappa Sigma house at Michigan and the Sig Ep house there as well (plus a few more I was in during a visit in high school, but I can't remember which ones! TEP I know for sure--which has since gone dormant--but there were 2-3 more I was in).
