I heard that poto was real good friday, and that ILRA is also in good condition. How the rain will affect the trails tomorrow is hard to say, but I'm sure that they'll be fine.
I rode A, B, and C loops saturday morning at Highland, and even though it rained hard friday night, the trail was in perfect condition. Not a puddle or muddy area found. A bit slippery on the leaves at times, but very firm around the entire trail.
Rode Novi on thursday evening, and it was it great shape. Even the PBR loop was in good condition. I expected that loop to be the loop with the most mud problems, but it was very clean. There was a few muddy areas found on the main 2way traffic areas, but that was about it.
