This weekend:
Trail and snow conditions are very hard to predict, after 4 years of snow biking at the mound.... thoughts for the weekend.
With the tree cover Blue Mounds can handle more sun and heat then other trails, by noon tomorrow it will probably be soft, if you get there to ride and you are sinking in and you can make a snowball with the snow it might be best to just do hill repeats :D . This is a little bit of a long shot, but Sunday morning the snow should be frozen again and if the trail does not get foot traffic or... if someone wants to get out for a great night hike, bring your snowshoes and pack the 7 miles in after dark. It will be perfect for riding for first thing in the morning.
This is all a guess at best.... bottom line, ride before it is over!!!
