More a set of guidelines to follow (an example)

Pretty common practice almost everywhere, unless it's private, or posted differently.

-Bikes yield to anything & everything, we're the low man out there.
-Downhill yields to uphill, except at DH only, & resorts.
-Keep singletrack single - do NOT ride off trail, making braids, this trashes the trail.
-If you can't ride, don't go around it, walk over.
-Talk to people, say 'hi' (chat up any/all the fair damsels you encounter on the trail.) Thank them for yielding, whether they do or not.
-Ride in control - I pin it when there's open trail ahead, but if you cant' see enough in advance (blind corners) slow it little just in case (I ring my bell coming up to hidden areas as well)
