I was up there today, coming in from the north (west? the Hwy 17 side of Summit, not from Mt Madonna). I obeyed the signs but rode from Highland, up Mt Bache to the gate, and then back along Loma Prieta to Summit. There were a couple of 2-stroke dirt bikes that whizzed past me as I lumbered along on my Wee Strom. The section of Loma Prieta running NW from Mt Bache back to Summit Rd was very nice with all the rain we've had lately.
