"MTB Jump", is that really the name on all those? Do they have signs listing their names? And are they really tourist attractions?

At the moment, there are not community supported tags for tagging mountain bike trail features, only the trail's way can be mapped with current tags.

In summary, the trail is tourist attraction enough, only things with official name names should be named in OSM, not named just so they get rendered.
