So Ellen called and said she was taking the kids to Wolf Den to go swimming and perhaps do dinner out at the Vanilla Bean and did I want her to throw the bike rack on and meet them out there. OK.
Nice ride from campus on backroads over to Goodwin SF where I decided to see what the Airline North trail had in store. I had heard rumors from some trail runners that parts of it were pretty rough, but hadn't been on it myself.
Basically unimproved rail trail - the ties etc have been removed, but the rest is rough - some soft sandy areas, plenty of muddy bits (playing dodge frog), and lots of rocky sections. But my 700x38 slicks handled things just fine and I managed 18-20km/hr on that section. Got to the park, rinsed off and had a snack, then a fine dinner at the Bean. Good way to end the week.
