Below freezing temps made for nearly perfect trail/traction conditions. The mud was frozen just enought to move like silly putty. At least one downed fir tree just before the descent to The Hood but easy walk over.
Snow caused alot of the smaller brush to hang loooooow so prepare for some snow down the neck.
A few mudholes still not frozen but not too many. Also remember it is DARK at 4:30 in the trees.
My front Deraileur froze and my pedal clips got plugged with ice a couple times but well worth the winter wonderland out there.
