For Beaver Creek Reserve, I added some trails to the North of County Rd K.
Problems:
With different zoom levels parts of the trails disappear, others reappear.
Most of the trails should be loops, connected to other trails
Where did I go wrong?
Wrong tags? not connected?
Maybe someone with more experience can see the mistake.

Of course Northwest not South West

Looks like the underpass already has -1.
(thanks if you added that)
