I went to Pomona (when Gregg Popovich was our basketball coach - for real) and still live in LA. Things are certainly different than when I went there, but it's one of if not the best small liberal arts schools in the country. Westwood is much closer to the ocean so that's why the swings are less. 40+ miles makes a big difference. Malibu to Agoura Hills is less than 15 miles and the temperature difference can easily be more than 30 degrees in the summer (like 68 to 105). But compared to CT, Claremont, CA is pretty awesome all year round. The downtown (called Clareville) is really cool - make sure you check it out when you visit. I would imagine if Pomona is on your list, you are also going to see Claremont McKenna and Occidental, although Occidentals surroundings aren't nearly as nice. Probably wouldn't hurt to put Pepperdine on the list as well. I would say the most gorgeous college campus in the country if you (he) are (is) OK with the very Christian focus of the school. I would be happy to answer any questions you have about Pomona and/or Claremont. I would guess that
@Gurleyman could provide even more relevant information than I can.
