You need to be more clear. We are not able to read your mind. At the time you posted, it was raining. I'm guessing more that one person thought you were asking about the rain. There were numerous posts about the very subject.
Most areas affected by the fires are still closed and will most likely remain so for some time.
MTBBill has a great resource page if you were unaware of it.
How does Sycamore do with rain. Its a block a way but if its like my backyard I would say 2-3 days after a good rain. Any experts know?
The park itself for the most part only needs a couple of days, but the area south of the gate back to highschool can be a gooey mess in numerous spots needing sometimes needing a week or two. Sycamore Canyon has a habit of attracting the type of rides that don't want to get dirty but want to ride after a rain. These folks go out and ride around all the puddles and widen out the trail and just make things worse.
