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