Ageing Snowbird Parks, Changing habits, preferences.

I found this all very interesting as we have been going south for over 10 years or so and have noticed that like us many people are going from campground to campground and sightseeing. Although we do (if the campground has it) sometimes join in a pot luck or bingo that's not our main interest. What we have found is the last 2 years we have had difficulty finding campground spots. Previously (going in Jan & Feb) we could pretty much drive in and get a camping spot - not anymore we had to reserve ahead - and in our case "plan" more. It's just a fact of life = We've traveled in Florida & sometimes over to TX & AZ.
We've talked about "finding a spot" we'd want to stay for a month, but haven't.
