Well winter is on its way :) which alsways means lots of snow and dangerous road conditions... Automatic Tire Chains are one way to help minimize the danger.
When I was in kindergarden I rode bus 119, a short Thomas International with a manuel transmission, and atutomatic tire chains. Automatic Tire Chains consist of chains that hang below the bus attched to wheels. When engaged, the wheels rotate down and make contact with the Bus's tires. The the chains are thrown under the tire at a syncronized speed. 172 later replaced 119.
