I got the chance to go out and do my favorite loop yesterday.  It was a nice, drizzly day with some decent rain by the end of the ride.  I was racing my best time from a couple of years ago, and was 50 feet ahead when I hit the entrance to Willow Creek State Park.  But, alas, that entrance had been fenced off, so I had to drop down Willow Creek Road until I found another entrance.  It ended up being some nice singletrack up the side of the hill.  That part ended up sending me off course, so the race was over.  The new route was a nice addition to the ride and I am looking forward to doing this loop in the future.
