Prenatal virilization. In the prenatal period, virilization refers to closure of the perineum, thinning and wrinkling (rugation) of the scrotum, growth of the phallus, and closure of the urethral groove to the tip of the penis. In this context, masculinization is synonymous with virilization.
[QUOTE=Greatnorth;481595]Well, usually I wait till there's a good 3-4 foot of snow because you don't want your skis to touch the dirt/ground or whatever isn't snow. Snowmobiles are made to operate on snow and that's all they should do. Really 3-4 feet of snow until you go snowmobiling??? They open the trails around here when roughly 6-7 inches of snow are on the ground. Never had a problem running my sleds in 6 inches of snow or more.
If snow continually melts as it lands, and the accumulation never reaches 0.001 inches (0.002 cm) on your measuring surface, snowfall should be recorded as a trace (T) and record in your remarks that the snow melted as it landed.
