Rode today with our guests Tom & his buddy Shaker. We rode up thru Phelps to Iron River... we put on a 120 miles. Even tho the trails are a little thin, they are all smooth and in decent shape - plenty of lube for the hyfaxes. We had an awesome ride even tho it was bitter cold. As far as bad areas.. dirt or gravel, didn't find any today, but the base of the snow is set up really hard. Sure had no problem riding on these.
