I do not think that motorized vehicles should ever be used off road on any public lands. I am a firm believer in leave no trace usage. I do get a kick out of walking by the 'gate keeper' newbies that put ladder stands on the entrance tractor lanes as close to the parking areas as possible and then think that they control the entire area. My concern with using the bike was if it would bother other hunters that hunted in deeper than the newbie 'gate keepers'. i looked at a fat tire Ralley at the local Ace Hardware. They are not so good on a parking lot, but how do they do on a muddy tractor path?
