I haven't ... so I'm riding with Western Wheelers on Monday, 5/28. We'll do both sides of Old La Honda ... short 30 miler.
If interested, we're meeting at 10 am at Gunn H.S. in Palo Alto (rolling by 10:15 am). This one has an address
780 Arastradero Rd, Palo Alto, CA
Now, I'll have to warn you this is a brisk group.
