My neighbor, who is a scholar, gentleman, and cruiser rider let me know there will be +500 hog 'poker run' north through Marin Sunday. That may make you want to ride south, lock all the doors, or go join the party.
A 100 cruisers blew by me going the opposite direction today going north. One found a ditch and three of them stopped to look at a lil' scratch on the pipe and blocked traffic in both directions.
Adjust accordingly.
