We go for an extended stay in Sacramento, once a year. My Wife's youngest Son (50) with his Wife, and a 2 and 3 year old, the oldest one is the Girl! They are just wonderful!
I can not stand CA! The scum that walk the streets, and my guns are in Orlando. The people you meet who are impaired?
The good news we drive a lot, ferrying munchkins to and from day care. My City Stick, is the only weapon, plus a real sharp folder ($10) local buy.
The main thing we do, is take the stress off our Daughter in Law, we shop/cook/laundry, munchkin bath and stuff. So Grandparent's are needed, I never had any.
Living in CA? Never.
