We're out on our 3rd trip for the season. No problems. Offices have you check in online or pick up your map and site/park info outside. Restrooms are clean (although we don't use them much). Pools are closed. Wear masks at grocery stores and order take out.
Am hoping parks stay open with restrictions as I have a big trip planned starting in Sept through the end of December out East and down to Florida for Nov and Dec.
