They haven't updated the Ont to WP trail 12 lately but usually when I check this they only update when it is necessary. I would say this is a pretty good guideline. I usually use the MSA snowmobile trail reports for the whole UP. I find them usually fairly accurate as the groomers are reporting. Hope this helps.
Next weeks cold temps will help freeze things over, currently it hasn't been groomed yet, hoping for snow this weekend, currently there is about 2-4 base with wet spots everywhere. Not good riding as of today.
