Every year hundreds of thousands of people flock to the Minnesota State Fair. One of the biggest attractions of the Fair is the ocean of heart attack inducing deep fried food on sticks. Even though the food at the Fair is likely to take a few years off of your life the primary health concern of fair goers appears to be second hand smoke:
The fair’s board of managers voted to ban smoking in virtually all open-air space on the 320-acre grounds starting with the 2013 Great Minnesota Get-Together. Smoking, already prohibited in fair buildings or in entertainment seating areas such as the bandshell and grandstand, will be restricted to designated outdoor smoking areas.
Risk assessment is hard.
