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.
In December, for instance, one in four years totals over 10.8 inches of snow. Another 25 percent of years receive less than 2.6 inches for the month. Similarly in January, fresh snowfall in the heaviest years amounts to over 12.8 inches, while the lightest years get less than 3.2 inches. New snow for February ranges from over 9.3 inches in heavy snowfall years to under 2.6 inches in light years.
