Don,
Please reread my first sentence. I am not a hunter. I don't even own a gun. The only thing I know is that
1. Hunters use ATV's
2. ATV's make noise
3. Noises frighten away game.
4. Some land owners restrict access to ATV's due to noise concerns.

So, no, I wasn't kidding. I was asking an honest question based upon my limited knowledge of the sport. If there is no call for a quiet ATV, then there certainly never will be one. You don't try to build something no one wants.

Thanks for the input.
