Adams Cty is open. Just head southwest a little and you can ride. Plainfield truck stop could be a take off spot. Not sure how the trails will be, but they are open last I saw.
Plainfield is in Waushara county. That particular stop won't work, but looking east from there possibly. Just nothing open close to Steven's Point the way it looks.
Try this website, http://www.travelwisconsin.com/snow_report.aspx , and click on the Snowmobile tab in the middle of the page. It shows which counties are open and what the conditions are.
Also, I heard that trails around Amherst (south of the Tomorrow River Trail) will be opened some time on Thursday to allow for sledding to/from the Portage County Ice Wars.
Just called the Portage County Snowmobile Trail Conditions hotline (715-343-6277). The recording says some trails in zone 4 may open later in the week. Keep trying the hotline for updates.
Got word from the guys plowing the parking area for the Portage County Ice Wars, that they plan to open some trails Thursday, guess we'll see how that goes, and hope we get a couple inches out of this next little splash......
