No more towing?

[prog.livejournal.com]

I notice that, at least in my neighborhood (Wilson Square), cars left out for the street sweeper don't seem to get towed as often as before. In 2003 I got hauled two or three times before the sweepers hibernated for the winter; last year I probably goofed as many times, but got only a ticket when I did. Judging by the many ticketed but otherwise unmolested cars I can see outside my window this morning, it looks like the start of another such year here.

Is this just my neighborhood, or has the city become less tow-happy?
