I got to wear sunglasses on tonight's ride! There appears to have been a dog mushing race on the weekend, the trails were rock hard and there was a bunch of trail marking stuff out. Also a lot of brown streaks.. thankfully frozen. The overflow is starting to encroach on the trails now.. it's so interesting to watch it just sorta appear since you never actually see it liquid and flowing.
I'm going to get my cross bike out of storage and take it for a spin on the mushing trails, hopefully later this week. Trails are ferociously hard packed right now and my 40mm tires on the cross bike should work just fine.
