Chuck,
Sportsmans Guide sells tree stand levelers that fit in the legs of a ladder stand. Each has a pivoting plate and holes so that you can adjust the legs to different heights. I drilled my ladder stand so that the clips attach the leveler to it.
When I went to Iowa, the stands usually faced up hill. The platform in front was 12 or so feet off the ground. In back of the tree it was 3 miles to the ground!!! I don't care much for heights either. Getting harder and harder to go over high bridges.
