kristenE,
Life in Erie really isn't as bad as people make it out to be. When you first arrive to the area in July, the weather is actually pretty nice, and you can go to Presque Isle Park to relax and look out over the lake. This year we had our first snow storm in late October I think, and it really wasn't bad. The thing with Erie snow is that you get it in small amounts (1-3 inches) frequently. Sometimes we will get dumped on, but for the most part it's small accumulations every few days. LECOM does a good job of cleaning the parking lot (better than the main roads sometimes).
As for where to live, Lakeview is one of the nicer places if you have a roommate (since it's only 2 bedroom apartments). I must advise against Granada. If you are willing to put up with poor management and less than stellar facilities (but a cheap price), then it's for you. I am living there now, but am looking to get out for next year. There are lots of places similar to Lakeview (Willowwood, Scenery Hills, etc.), just depends on how much you're willing to spend and how far from the school you'd like to be. I definitely advice going to look at the places before moving in.
As for stuff to do, Erie has a lot for a smaller city (4th largest city in PA). A few movie theaters, a large mall, lots of shopping centers (Peach street is all shopping centers with tons of places to eat out), Presque Isle State Park, Erie Zoo, a comedy club, numerous bars and pubs, a dance club (Metro) and anything else you'd really need or want (I think). It's not going to be like Philly or NYC, but I think it has a lot for where it's located. It has a lot more than my hometown anyway.
If you'd like to know anything else, let us know.
