Ok, it’s not PB, it’s got no beach… but I love living in the college area for pretty much the same reasons. Ya get to watch the kooky college kids get into trouble (lingerie parties in November?!)and there’s plenty of stuff to do within walking/biking distance: the school has a full blown gym, pool, bookstore, library, and all the other university facilities, there are dozens of mom+pop as well as chain restaurants, shops, coffee houses, grocery stores, and so on. Stay west of 70th, and not more than a couple blocks south of El Cajon.
The college kids CAN occasionally get a little noisy, but shouldn’t be any worse than PB. Petty crime here seems to be a little lower than PB – bicycles don’t disappear off the porch QUITE so often, fewer bums, etc.
