Sean, yeah you are right on, great ride.
Tony, Maryanne,and I met at 9:00 it was a crisp 35 degrees according to my cars thermometer, but bright sun, we hit the trails right away, Tony knew the place like the back of his hand and did a great job leading the ride, he had us flying through the rolling single track in no time, and was patient enough when we slowed him down a bit, I have to say that the drainage at Hartshorne is amazing, there was no mud to speak of, and the trails were just tacky enough that you could blast through the corners with great traction, lots of ups and downs, so despite this being right near the ocean, the park is NOT flat

.
We rolled back to the car after one lap to pick up some water, and rolled in for another lap, where we picked up another rider 2nd lap was a bit shorter then the first but we were well warmed up and had a blast flying through it.
It was great meeting and riding with everyone, and thanks to Tony forleading a great ride.
Acording to Maryanne's computer we did 21 miles.
