Passport America Lifetime, Thanks all, I'll pass

I use Passport every time we travel. We very seldom spend more than one day at an enroute stop towards our destination so we are just looking for a place to park and sleep. I have found that through the years, Passport America has more than paid for itself. Some of their parks are great, and some of their parks are not. Not much different than KOA in my opinion. Personally I don't feel that a lifetime subscription is worthwhile for us. To me it is more about the long term viability of the business rather than the few dollars saved.
