Is there a sign that says vehicles will be towed from the parking lot?

Yes because of the stadium across the street

Every business and appartments in town have a contract with some towing company to tow away nuissance cars, if you are not a costumer, park overnight, have a for sale sign, your car looks old and abandoned or park in handicap areas or no parking zones can be towed, it cost 300 dollars to get it out, follow the rules park in visitors parking, get the sticker if you are a tenant, do not asume that you wont get towed just because you parked on your friends spot. Save yourself 300 dollars

When a game is going on
