BWR alum here and was my favorite dorm out of the 3 I stayed in. Linden is a close 2nd for me and my other stay was Towers and my building (Storms) was imploded years ago. BWR my freshman and part of sophomore year. The old RCA buildings have some huge rooms you can't get in some of the other cookie cutter sized dorms but you either luck into one of those rooms as a freshman or request one when you re-enroll the next year. Still though even that standard sized rooms in the old RCA area usually were bigger than most rooms on campus. Being all male dorm didn't bother me, Oak-Elm is right around the corner and all female and most of the floors usually wound up doing a brother/sister floor arrangement for social activities.
The other 2 places I was an RA in, ironically I had one of the better behaved floors at Towers in what usually was a big party complex then my last year was RA in Linden and got stuck with a horribly behaved floor in what was a really tame building otherwise. Not familiar with the newer dorms that went up after I graduated in 2002. I think I saw that all the lofts are now provided in all the dorms now? In BWR some of the lofts basically stayed with the rooms because someone custom built it to maximize space in a lot of those odd shapped rooms. The best room on campus I thought was the 3 person room on 2nd floor Birch right inside the main entrance. It was 2 rooms, someone built a loft that went in the smaller room that lofted all 3 beds and had enough room to put all the desks and dressers underneath it making the larger room pretty much a living room. Needless to say it was usually always occupied by upperclassmen and made for a popular hangout area on the floor. 2296/2298 was the room: -

Won't lie but the more I go through Ames and campus these days the more jealous I am of all the new stuff students these days have available to them that we didn't. Granted I'll trade that for lower tuition costs too.
