Sunday in Philadelphia is otherwise known as "park wherever the hell you want day." Actually, in some neighborhoods every day is "park wherever the hell you want day" as the primary job of local politicians is to ensure that no resident ever pays a parking ticket. In the rest of the city there's an informal understanding that anywhere in the general vicinity of a church - just about everywhere - you can park anywhere, including on sides of the street where parking isn't normally allowed.
Normally this isn't a big deal as I don't own a car and don't drive much. But today I rented a car for a couple of hours to run some errands and had to navigate the maze, which was made even worse by the still lingering piles of snow and ice.
