I have a three-ring binder with various bits of RV-related information in it. On the last two pages, I have various membership cards in plastic, including Good Sam, Passport America, KOA, Disabled American Veteran, 100% disabled vet card, Golden Access card,etc, etc. When I check in, I show those and ask if any of them apply. Never can tell what might apply. I got a 50% discount at casino based on my Golden Access card.
