SISCRA is open to all, but primarily attended by 55 and over campers. There is a monthly option, and many retired folks have established this great summer community. The U.S. Mail even delivers there. Thursday nights have bingo, Saturday nights live entertainment and various dinners in the REC hall. Members get a discount on camping, money well-spent to maintain the grounds. Both tent and electrical sites are available, 3 other nearby reservation sites were full. I had thought the campground was right on the water, but is not. There's a walking trail with some great views. My only complaint is that from 7:30 am until late afternoon, there are non-stop golf carts and ATVs doing circles around the campground. A front-loader went past my campsite repeatedly, I stopped counting at 16 times. I left a day early because at 6:30 a.m. the neighboring rancher shot a shotgun VERY close to where I was camping. It is not hunting season, I believe he either shot a cow, a predator, or both. I may return another time, it is nice that showers are included. Very close to a favorite hot springs, and just a few minutes from nearest town.
