You need to
park a car for the weekend. You find a parking space signed "2-hour
parking M-F, 8am-6pm" with no other restrictions. You call the city
and find that overnight parking is allowed on this block. So, what is
the maximum amount of time you can leave your car in this space without
getting a ticket?
month's riddle answer:
66 hours. You
can park in the space from 4pm Friday until 10am Monday.
