You're going to like East Shore. I spent 3 weeks there in the Spring while my house in Azusa was being prepped to sell. I was still working at the time, also in Azusa, and it was an easy drive in and out of the park.
I remember coming back one day after a long day at school, and the guy (I think he was a work camper) at the kiosk smiled, waved at me, and said, "Welcome home." I cried.
There are lots of long-term residents there, and the park is well-kept. Busy on the weekends, but quiet during the week.
Enjoy your time out here. Hopefully the weather won't be too hot.
