There are some excellent opportunities to hunt public land near you. Tri-County FWA for instance. And they offer jump-shooting sites. Which means you don't need a boat. All you need is a handful of decoys, a bucket to sit on, your gun/shells, license/stamps, camoflauge and a ride to the property.
But it would be wisest to hunt with an experienced waterfowler a few times and then venture out on your own.
Careful though, this sport is incredibly addicting. Like to the point that you are browsing hunting forums 5 months before the season starts....... I've already been rearranging decoys, cleaning the boat, motor maintenance and planning this falls hunts. It's ridiculous.
