And so it is that now -- the end of the current academic year -- at least one more has gone missing -- the one at C and 6th. And the one at B and 6th has been the subject of energetic effort that failed but came close (images 1 and 2).
The other day someone faulted the City for not having theft-proof screws on the signs so that people could not so easily detach them. This person may have a point, but the sad fact is that many signs are taken by brute force without the nicety of undoing screws. Thus, the entire sign array at C and 6th is now missing! And the one pictured here almost yielded to brute force.
