You know those signs that say "Clark's Beauty Salon Only - Towing 24 Hours" behind State Street pub? Yeah, they're not fucking kidding. 10:30 PM, those motherfuckers have been home for five and a half hours, and you'll STILL get towed.
I'm pretty sure the impound place just cruises by every now and then to see if they can get a big haul. Fuckers.
