I have a sister in Rancho Cucamonga. It is a nice and quiet place, I really like it. I almost moved their until this job came through here in TX. I would move to Rancho in a hard beat if a job came up. I just had a semi friend get a job in Upland and she was born/raised here in TX. I spoke with her just recently and she loves it. Now, Upland is between LA and San Bernadino.
The sister is talking about moving here to TX. She has a beautiful home, affordable, more than LA. Unfortunately, it takes her 1 1/2 hours to drive 24 miles.
I believe we have a few members here from that area. Kustom? Harvey? I can't remember right now. Anyways, try them. I know that Anne (N) is a valley girl and she moved from Ft. Worth. Stand Bear Trading is in the valley, but check in with them.
Good luck.
