Probably sidetracking the thread but…One of the loops that I absolutely enjoy is …
From sidnaw take 8 west to trail 107 ( a little hard to find this turn, but once you find it, you will hopefully not forget it in the future)
107 is an awesome trail with beautiful big pine trees as you wind up and down hills through them, 107 runs into trail 2, which you would take a left on towards iron river, (stop for a tank and tummy if needed) then head back westward on trail 2, then head north on trail 15, this trail is not for the faint hearted. approx 45 miles of everything a snowmobiler would want and dream of, (straight aways, twisty tighty, and lots of beautiful scenery). then back to trail 8 east to sidnaw. It’s approx 100 miles of snowmobile heaven
Hopefully this could be included in your plans
