As I've recently retired, I've found it interesting to visit places during the 'work week'. There is certainly a different clientile around and about during the day during the work week. I've been frequenting the Musuem of Fine Arts in Boston lately, and now find that I really need to pay attention to those 'every other Wednesday no parking from noon to 4' signs. As I came out from the MFA, around a quarter to noon, it was interesting to see the line of tow trucks ready to begin towing on the side streets.
Never had to worry about that in the past when I usually was in the city after hours or on weekends
