It's cold and slippery- duh.   

The main loop is the most dry.  Roller Coaster and Lake Loop are the most wet.  The connector from the main loop to the Lake Loop is really wet.  Since it was so cold first thing this morning lots of the trail was crunchy, I assume it will get more messy when the weather warms up.  No major trees were down, the trails were clear.

I rode everything(carefully), and it was awesome, but still lots of 2 wheel slides.  Bike was covered in frozen mud by the end.   

Dress warm- my feet never got warm.
