I know what you mean about bodybuilding.com, I've seen it, too. Sad. You're right, this place is more laid back and diverse. Not all of us are strict vegans, so don't worry about it. We're here to learn from each other.
Explore the threads, get some ideas, try 'em out. See what works for you. Post pics and/or start a training journal if you feel like it. From one 40+ lifetime weightlifter to another, don't be so quick to blame anything on age. I've seen way too many examples of starting late and succeeding, amazing turnarounds, and 70+ bodybuilders who could crack a walnut between their finger and their thumb to doubt that you can do anything you want to once you find your method.
PS: How far north in Cali? I'm just above you in Portland, OR. All hail Trader Joe's!
