Delightful

This park is mostly a campground, but it has lots to do. The spots are bigger, somewhat private and under the trees. They are desperately like trying to keep things watered and are succeeding, and it's nice and green.

They are next door to a winery which is quite nice. And I have a feeling i'm going to have dinner over there.
