We are working to add another color for freeze thaw days. Freeze thaw is hard for us, as the trail my be fine in the early morning, or even later in the day, but terrible as it thaws.
Riders out early often report back that the trails are great, and beginner riders reading the posts head out to a trail that is now a thaw'd out mess.
Until we get the new color, lets stick to red on freeze thaw days. experienced riders who know how to use the early or late frozen time, can do so.
