Dream - Biking Guide

I have left a dream-forgotten situation in the Richmond and am on a standard bicycle wending my way through a series of right-angle wooden covered tunnels as an approach to the GG Bridge.  I encounter and avoid oncoming tourists who may or may not be on the right path, as it is narrow and does not seem to be designed for this double passage. I am not traveling at top speed so this is more of a pleasant surprise when they pop up from around various corners. After what seems a long convoluted and Byzantine journey, I finally come out near the ramp to the Bridge. I must walk my bike and avoid a muddy patch of long grass that leads down to a path. Tourists from both directions are milling about and I give directions to a few who I overhear talking. I correct their confusion about the name of their location, but restrain from telling them the history of the buildings in the Presidio and the architectural timeline they portray.
