Because of the freeze-thaw cycle of late winter, pavements all over crack and as vehicles drive over them potholes develop. This is true of city streets and private parking lots. Who does a better job of repair?
Some of the streets in our neighborhood have a few small potholes that can be easily driven around. On the other hand, the Mt. Royal Shopping Center parking lot has many huge, axle-buster holes. Driving around these is like driving a gymkhana.
I bet the city potholes will be fixed before the shopping center sinkholes will.
