I'm with lorne and farmer on this one. If you cant retrieve the bird dont hunt there. You cant be planning on best case scenario. I'm sure you can find a spot where you can just wade in and get the birds or get yourself a small boat. I picked up a small punt already camouflaged off craigslist for 100 bucks a couple years ago and it opened up a lot of areas for me. Just keep your eyes open for deals
