Winter riding

[Rage]

First thing to remembers is that you should never ride natural surface trails in the winter when the temp is above 32.

The ground is a pretty big heat-sink, so just because the air temperature is at or below freezing it doesn't necessarily mean the ground is frozen. Regardless of the temp, if the ground is soft please don't ride - much damage can be done if the top surface is thawed.

Give it some margin: 27 is the new 32.
