Croc - That sounds like harrassment. The FWS guys I guess are patrolling the area they are supposed to but I would figure the sheriff deputies would have a lot more to do on a big weekend than watch one airboat for nearly an hour. Talk about pissing away taxpayers dollars.
Heck, I could understand why you were the only one out if yall get that type of treatment. All of you fellows need to carry a little book and pen in your front pocket. Write the names down of the officers each time they stop one and take some notes. I would bet if they are doing this to everyone, then after a while you could get some politician to notice a pattern to airboater's harrassment.
