Is this guy swimming to his duck blind faster than a boat, or did he strap himself to a mini-sub?
Here's a guy that knows how to get around a swamp. All you need is a little ingenuity, some wrenches to turn, and you can follow this guy's lead.
You'll want one of these.
If you can keep the air flow going to your engine, you can keep your engine running, regardless of environment. This buggy swamp in disguise makes this video a fun one to watch based on the its surprising machinery appearing out of the swamp.
I'm willing to bet that somebody somewhere has shot a duck off one of these machines just the same. Just don't tell the local sheriff.
