Popular Routes
It would be very useful to be able to upload a GPX file containing waypoints (which would be mainly coordinates of geocaches) onto the map so that the great tools on this site could be used to 'plot a route' (Pardon the pun). Often the route to take is obvious when navigating from waypoint to waypoint (cache to cache) but it would be much better to see the big picture before setting off in order to take the best route between waypoints and avoid obstructions, steep sections, etc. and perhaps the best route to get to a waypoint that is slightly off the main route.
Geocachers often go out in groups. It would be great to pre-share a route before setting off on an adventure. The route could be pre-loaded into Garmins and mobile apps like c:geo. I'm sure this would attract a large audience to your membership if implemented.
Thanks for this feedback Billy.
