n8ly, my wife is in a wheelchair and one of her publications she reads promoted having developers spend a day in a wheelchair a while back. Go rent one for a day from a medical supply store and see what it is all about at the facility now. It will open your eyes to their safety.
Norm, got anymore picks of that wheelchair accessible dock? I am going to be building a version of one. I chose my property because of the access. They now make a polyurethane type product that solidifies soil into a solid surface similar to asphalt: http://www.polypavement.com/new/index.php
I eventually plan on opening my property to occasional handicap groups for fishing, a nature trail, and possibly hunting on an individual basis.
