Is there really a peak here named "Fish Ranch Peak"? There does appear to be small a peak here with the transmitter but I can't find a single reference to that name anywhere (literally zero google results even). Old usgs topo maps simply label this as "Communication Towers".

Also, the height is clearly wrong. Probably a feet/meters issue.

The big sign here at the end of La Salle says "Montclair Railroad Trail", not Shepherd Canyon Trail.

changeset changeset/156505729 seems to have marked this bridge as access=private should it instead be marked as access=permissive since there are no barriers or signs at the start of the bridge from what I can tell that indicates public travel is prohibited, seems that only happens at the gate house past the turning circle. Verification may be needed here.

The dotted line following the railroad tracks is now an open bike/pedestrian path. It starts at Corona Rd. in Petaluma and runs northbound until Petaluma Hill Rd. in Penngrove

Suspicious-looking separate cycleway added here with cycleway=lane; needs to be checked/fixed.

This intersection is incorrect due to recent construction changes that are permanent. Drivers can make a right turn from 27th street southbound to 24th street westbound. However, it is not possible to enter 24th street westbound while traveling southbound on Harrison.

Are all these trails in Dimond Canyon / Dimond Park really cycleways? They look like hiking trails, or ordinary park paths not really designed for bicycles further south.

Helepad changed to highway=elevator.
