Rode from Canal to 27 and back on Sunday via Blue and Red, with a short detour onto yellow (I think - it was our first ride at 6 Mile).
80% of the trail was just about perfect. Tacky with no sink an loads of fun. What we believe was the yellow trail (cut to the right off blue from a field) was disastrous - mud up to the hubs. There were a batch of other spots with some thick ass mud, but in m our defense these areas were WELL rutted by what must have been dozens of previous riders.
Overall it was still a really good time, though the bikes (and use) were completely covered in mud and muck by the end, and the pace was slowed quite a bit.
If this week holds out for the most part, that run will be dynamite this weekend...
