ForEVER, I weighed out the option of buying a GPS or iPhone to assist in those "wandering" motorcycle outings where I'm just riding to see where I end up (yes, I hate just going back the same way I came, LOL).
So I'd use Navigon for the Summer trip of a lifetime that I've been planning soon, a trip east to the "Dragon's Tail" (curvy twisty mountain highway ride of a lifetime) before dipping down south to the Ft. Lauderdale, FL area to visit my dad. And, of course, a completely different route back home to Oklahoma!
