Welcome Rob, my name is Mike and I'm disabled also and I live in East Central Florida. I hope that you know this, but just in case you don't. In Florida all of your hunting, fishing and wildlife management area permits are all free for disabled residents. Here's the link.

I hunt a lot on WMA's and I have a permit that allows me to drive offroad while hunting in these areas. It's called a "Special use vehicle permit", get one because it will allow you to drive closer to your stand. Normally on a WMA, vehicle use is restricted only to the main roads. Meanwhile these areas are crisscrossed with access roads and fire lanes, and the SUV permit lets you drive on them.

If you can't walk at all, or if you need assistance to walk, Florida will issue an Alternative Mobility Permits (AMP). If you get a golf cart, atv, or bad-boy-buggy type ride, that you can hunt from.
