Because the truck stops are going to be major vectors. Once one truck stop becomes hot, it will spawn hundreds of cases, those cases will then create many other truck stop hot spots.
Truckers use the bathroom and shower in truck stops. Each shower room has its own toilet. Maybe 150 truckers will shower between the 5 or so showers during the day at a busy truck stop. Maybe over 1000 will use the restroom there in a 24 hour period.
