Also, there are all the points raised when I complained about "moved before sweep" - a friend's car was still parked n the street sweeping area five minutes after it went into effect, and got ticketed as we walked up to move it. By the way, he successfully contested the ticket.
Some of the valid points in that discussion included: If the ticket writer can "un-write" the ticket, there is incentive for bribery, blackmail, and/or threats. Have the ticket writer annotate it "moved before sweep" and then contest it.
If you get there while the PCO is still there, parking pass in hand, have the PCO make a note on the ticket (I think they do this electronically?) saying that you came out with a visitor pass. I'd bet that just as with moving the car before sweeping, this will make it far more likely the ticket will be dismissed.
