Unfortunately, double parking has become a Columbia tradition. Quite often, drivers too lazy to park properly simply park in the street, blocking traffic and creating dangerous conditions. As shown above, the situation on the 200 block of Walnut Street was especially challenging yesterday. The driver of an SUV (center) had to wend his way through a veritable maze of vehicles - three cars and a truck - that were double-parked. One can only imagine how bad conditions will get when the impending snowstorm hits the area this weekend.
