Just like Sprague03, I didn't choose East Campus either. But I'm so glad that I got put there my freshman year. It was such a great feeling when compared with the rest of the campus, in my opinion.
I felt like I was in a place that was super-historic (like an Ivy College), with the buildings that had been on campus since the very beginning. The scenery of Horsebarn Hill was awesome, even if the smell sometimes wasn't. The population was a little more eclectic, which was cool to me. And I didn't mind the walk to the chemistry building, which would eventually end up being my major (although as an engineer in my freshman year, the walks were a little brutal like you said, mostly in winter). We had the pool hall in the basement, next to the work out gym and the puppetry studio (I think they may have moved the puppetry studio to the Mansfield Depot now). And the open quad in front of Manchester Hall was great for playing pickup football, ultimate Frisbee, or soccer games on any given day. And of course, we had the Dairy Bar and Store 24!
If I had to do it all over again, I would still pick East Campus over the rest of them, even with the knowledge that South is a much newer complex...
