The sport of using large blocks of ice to reach relatively high speeds down a grassy hill. The only required materials are Blocks of Ice, Towels, and a Grassy Hill. Simply sit on the block of ice (with a towel over it) and slide down the hill allowing minimal friction by using smooth ice and short grass. Let Gravity do its thing.

Often times it is called "Reverse Sledding" because of its popularity in areas that do not recieve snow. Ice Blocking has a huge following among California Teens.

Ice Blocking can be used as a great first date, or hours of endless fun with old friends.

Unfortunatley many parks have banned the sport and labeled it as Vandalism for its ruining of the lawns. However late night runs in the sprinklers have proven to be most fun and least obvious to law enforcement.
I had numerous bruises, but great memories after a night of ice blocking

Sledding for people who live where it doesn't snow. Most popular in California. Riding down a grassy hill, on a giant block of ice. Make sure there is a towel in between the ice the pants. Beware of "it looks like you just peed your pants" water marks. Comments may follow.

Ice Blocking is best to do at night because the level of bamfness increases.
