Any thoughts on making this a semi-regular MOB ride? Organize a few in the beginning, then just let it become a whoever shows kind of ride.... same time & place, just show up and roll out at "X" time. The route, "Paradise Loop," is well known throughout bay area cycling circles, so maps and route directions are readily available if you need to take a look. Bonus: There's cafe's conveniently located along the way... right about the spots where you start wishing you had a coffee or a danish.
As Desmostro and I were discussing on our ride, it's amazing how much your moto skills can be improved from cycling, and vice-versa. [moto]
If you're a tad faster, then maybe head out 10-15 minutes behind the group and play catch up. If you're a bit slower, leave earlier and let the group catch you and pull you along.
Not trying to set this in stone. Just making a suggestion, so those of us that are multi-two wheel disciplined can get some good MOB saddle time all around.
