Went for a 30 mile ride yesterday with my wife. We rode a route that I've ridden several times, although a first for her. At one point we stopped at the top of a hill under the shade of a tree to rest, next to a paved road that turns off and winds up a hill into the vineyards. I saw a cyclist disappear around a corner which got me to wondering where this road went. I pulled out my cell phone and loaded the GPS app to find my location and saw that the "unknown" road made a nice loop and rejoined the same road we were on a couple miles ahead. By this point in the ride my wife wasnt particularly interested in riding more hills, particularly if the road was unknown. She carried on along our route and would wait for me ahead where this new road rejoins. Off i went, up, up, up. Great views of the valley, the vineyards and orchards below. Two miles into the loop, according to the GPS i should be approaching the original road only to discover the road ends in the middle of a vineyard. My GPS shows the road as continuing, but it wasn't anything more than a tractor's path at best. I phoned my wife, who was already wondering where I was to let her know that despite only being half a mile or so from her that I would be riding back the way I came. Can't say that I was disappointed by the adventure, just a little surprised by the lack of accuracy in the GPS mapping. I'd ride that road again if even just for the views.
