Our snowmobiles have been in hibernation for the past couple of seasons (hoping for a deep snow now, because theyre about to come back out of the shop). Fresh tune ups, ready for fresh powder..Weve had a dozen sleds over the years here at camp, from numerous eras and makers. (A few of them here). Our favorites to date are the Mercury 1970 250E and 250ER. (David taking the 250E out for a spin the last time we had it running).
