That makes sense -- the top and bottom of a climbing route should be two nodes separated by a way which indicates that it's fairly difficult to travel between the two. On our 2D map they'll be nearly on top of each other, which is correct but a bit difficult to visualise. Perhaps the ele=x m tag would be useful here - so that if someone actually tries creating a 3D map of a crag they'll have data to work with...<br>

</div>Having thought more about this, my proposal has a problem: There is no way<br>
to show the difference between a path leading to the bottom of a route and<br>
the path leading to the top of the route. I'm starting to think that for<br>
routes which do have a path to the top we need to have a node for both the<br>
top and bottom with a way between them, even though a lot of the time<br>
these nodes will be practically on top of each other...<br>
