There will be no snow in heaven. Contrary to popular belief, snow does not clean the earth any more than rain does. Snow does, however, show dirt and mud much more easily than rain does, giving the appearance of filthiness. It is obvious from studying the human body that we were not made to experience bitter cold. Any sport that can performed on snow can, with minor modification, be performed on water or other surfaces.
Skiing become water skiing.
Snowboarding becomes bodyboarding or skateboarding. Snowmobiling become jetskiing. Snowball fights become food fights or water fights. Think about how sick people get during winter. Think about how the suicide rate climbs.
