When Allan and I were married, we went backpacking. One of our stops was at Ogallala Lake in Nebraska. It is a park where you can camp on the sand dunes. Unfortunately, after getting our car stuck (and unstuck) in the sand, we noticed ominous storm clouds, so we ended up in a horrible hotel, made worse because we both really wanted to stay at the dunes.
On this trip, we decided to try staying there again. After exploring, we could not find anyplace that looked like what we had discovered years ago. We did learn that nearby Lake McConaughy also had sand dunes that we could camp at, so we stopped there.
The kids enjoyed camping on the beach! If we had more time, we all would have loved to stay and explore for a few days. It is on our be-sure-to-stop-again list!
