Just curious about "Passport America"

If you travel by RV as little as a week, it will more than pay for itself in savings. Of course there are black out places and dates but campgrounds find Passport America a blessing in the slow season...filling spaces that might not get filled at all.
It would be hard to lose if you stay in commercial campgrounds. If all your camping is Federal/State type campgrounds then it would be of no value. For that the Golden Age is a definite asset....for as long as its continues to be in existence. Rumor has it that it may be on its way out.
