La Verne, California -- recently rated as a top-10 city. The neighboring city (Claremont, which sponsors our bike group) was designated a Bicycle Friendly City by the League of American Cyclists, and was selected as the Stage 7 host for the 2011 AMGEN Tour of California. Both are college towns with a small-town feel.
I've been to Claremont. I wouldn't call it a small town, but then I live in a small town of 3200 so my sense of small might be skewed. I did like the area around Claremont though with easy access to Mt Baldy.
