We are brand spankin' new to this and are research/shopping for our GPS. Haven't even gone out yet and we are excited. My wife has been wanting to do this for some time now! We think it is another great way to spend time together, have fun, get some exercise, take our dogs along, have fun, get some fresh air, explore our area, get outside, do on day trips and vacations, have fun and have fun.
To repeat what someone else in this thread said - who cares what other folks think if you are having fun and not hurting anyone?
GO FOR IT!!
