We had a great time at Mary Anne's plan and she is a wonderful, super responsive host. We stayed here for the July 4th weekend, and actually camped outside the house, while other family members stayed inside with the air-conditioner, as the temperature was nice and cool from 9 PM - 9 AM. The air was clean and there is no light pollution, so we didn't put on the rain cover and enjoyed looking at the stars. It is only a 10 minute drive to Lake Camanche South Shore we were able to get one of the last tickets for the day, as we arrived at 9:30 AM (they have a capacity limit of 150 ticket/day, no re-entry). We also went to the Mokelumne River where we enjoyed fishing, tubing and just relaxing on the river bank.
Useful tips: Bring a small blow-up pool, foldable/pop-up shade (useful at the property and the lake) and a Patio Misting System which you can hand around the pop-up shade.
Internet: not good for zoom calls, but you can stream videos. Disconnect from work!
Thank you Mary Anne, we will definitely be back!
