New Brunswick Snowmobile Trail Conditions for Trail #42 near Doaktown as of Jan 17th . Trail 42 from Blackville to McGivney is in excellent condition as well as #58 from Blackville to Serpentine . #42 was groomed just yesterday and after the 2 inches of fresh snow last night it is great going today . We have a good heavy frozen base down now . Please be cautious of river and brook crossings that are not bridged . The weather is still fairly moderate so it is not safe to be on ice yet .
