We're riding it tomorrow. Like BW mentioned, it takes a ton of rain to kill the old school, less-ridden trails, HKSP included. We are bringing a handsaw in case there is some small stuff down, and will make a trip back there if there are any big ones down, to get it all cleared up prior to the EtTR for Feb.
I don't think any of the regulars (us included) have ridden there in the past couple of months, so no insight as to current conditions. I will post up tomorrow night.
P.S. I find it nearly comical that HKSP is now considered "old skool". It is barely 10 years old!
