We have been finding the same thing. Except for the attendance at EAA AirVenture Fly-in, which exceeded EAA's expectations, we've hardly seen any RVs on the highways in WI, the tourist areas have had very low attendance (choices of seats, parking, activities, etc. do not have sellout issues), and it wasn't until we got to La Crosse that we had full campground issues. The park we are in is right on the river, just outside of downtown La Crosse, wooded but with windows in the trees for satellite, a few beaches and a boat launch. During the week, it is almost empty, but fills up with mostly locals on weekends. There is a county park downriver about 3 miles with 400 sites and it is sold out for this weekend, lots of space yesterday tho.
