Passport America and its ilk

We've made our money back on PA in one stay, it may take some a little longer, like 2 or 3 stays, but a 50% discount is Very much worth it to me, as long as you read and know the restrictions ahead of time, you won't get blindsided, there are some on here that say there are no PA CG's where they go,with almost 2000 CG's, I find that hard to understand. I read one lady who would not re-new her membership because there were none near where she camped, (she only camped 20 mi. from her house).
It's a tool, we use it in conjunction with Good Sam,& America the Beautiful Senior Pass, between the three, we save a LOT on CG fees.
