I think I may have found a loophole in the system. It says a lifetime sportsman's license will work for your riding license and you only need one license per vehicle. If you know about Tennessee lifetime sportsman license they can be very expensive the older you get, into the thousands, but they are cheap if you are younger than 3yrs old it's around $600. So I guess if I didn't hunt or fish I could use my daughters (she's 2.5yrs old) sportsman license as our riding permit if she's riding with me? I would think so. $600 may seem like a lot for a huniting fishing and riding license but she's less than 3 and will get our money back by the time she's 8 if we were to buy her a hunting and fishing license every year. she could live to be 100yrs old and the $600 for the lifetime sportsman's license will be a great investment for her.
