Warren smowmobile crash (copy)

A Laconia teen was badly hurt earlier this month when he lost control of his snowmobile on a trail in Warren and crashed into a tree. Operator inexperience was listed as one of the reasons for the crash.

A New Hampshire winter outdoor activity popular with experienced riders and first-timers alike has been put in the spotlight recently after two Massachusetts women died from injuries suffered while snowmobiling. Both were inexperienced riders on a rented machine, according to officials, calling into question the rental process and safety of the seasonal past time.

Shawnee Hollis, 39, of North Brookfield, Mass., and Stacey McGarry, 56, of Littleton, Mass., were both killed in snowmobile crashes on trails in Coos County within a month of each other, the New Hampshire Fish and Game Department reported.
