I shared some knowledge that blind people may have.  Back at .., she introduced me to B.. who works at ...  Handshake.  <A little later:  weird talk about an interpreter for her.  Shruggable with my current exercise:  being blind to people's ignorance.>  A little later, at ..:  "Now we must depart.  Be careful about the cars," 'or something'.  Later, I made it to ..th, after doing a little solo-work without B..'s help.  First day too, gosh.  I'm 'just' now learning to recognize a little more detail than before.  Southwest-North area of the .. & .. intersection:  I made it there after listening for people and ..s.  There are 3 metal p..s kind of close together at that .. area.  ... of the intersection one could perceive, after hearing the cars, that there is a building to the left, cars drivable to the right.  In fact, there IS a building to the left.  Good thing people talk, so I could hear them coming.  Also, I could hear their footsteps <if audible>.  After a ways, I went slowly to the right and felt for the curb.  I found it, having some good idea about distances.  A little later, I think I stepped on a <s..> m.. g...  Good thing I had sight here in .., before today; otherwise, I would've probably just thout it was a g...  Before that, I felt for some cracks in the sidewalk, again hoping to equip myself with means for senses of direction, which would be or is according to my sensory or otherwise perceptual memory.  A little later, knowing about the building corner ahead and to the left, I turned diagonally to the left, then being on 18th St., west of ...  Of course, as I am blind, I'm not saying I went to the road.  Really, I went to the sidewalk south of 18th St. :)  On the sidewalk there, I felt for cracks in the sidewalk after a little while.  Also, I felt a grate or 2 <according to my perceptions>.  It was interesting, at a <city> street corner, to hear the cars to the left and a ways before me before crossing the street while hearing engine sounds to the left.  Actually, though, another happening that helped my decision to go across the street was that a bus was heard passing by, going from west to east, and it was slowed to a stop soon later, a little behind me and to the right.  If the bus had to stop early at the next intersection, then maybe the cars a ways before me weren't going anywhere for a little while, and I really should say that I heard at least one car to the left come to a complete stop.  I went for it, successfully.  Just a little later though, I somehow sensed that a bicyclist came swinging 'around' the <sidewalk> corner of the next city-block intersection.  To confirm that imagination, or at least intendedly, I slowed my walk and listened for swiftness or other speed of bicycle wheels.  Hearing faster-than-walk-pace circular-directioned wind, or something like that, though it wasn't very audible, I went to the right a little, and sure enough, a bicyclist', or someone else', passed by, on a bicycle', or something else'.  A little later, I went to write about the previous events at the Ta-C.  Rain started a little.  I didn't go for any darn revolving doors, and the door I tried was locked.  I went to the front, or .. St., side of the Ta-C. 

Some quick advice for blind people in ..:  Best time for travel downtown:  Morning-time, maybe 6 a.m., with a guide-for-blind or slow movements, care, a degree of caution, and preferably a good memory.
