I live in Cambridge. All places I've lived in Cambridge were within a 5 minute walk of a publicly accessible pool. Before I had a car for outdoor climbing, I took the commuter rail to see local towns or got a ZipCar and split the cost with friends.

These days, most of my trips are on my bike. Anything I can round trip within 50 miles round trip is fair game. My roommate made it to Cape Cod a few weekends ago, but he's very athletic.
