I bought a GPS to go geocaching. Since I purchased it (3 days ago) I have come across a mountain biking site that puts in some coordinates to follow a trail (4 or 5 spots on a 14 mile ride). My question is this: Would it not be reasonable to save the whole track of a ride and post it somewhere so that you could easily follow that ride? This may not even be the website for such a question but you folks seem to be dialed in on the GPS thing, so I thought I'd give it a try.
