I have seen full sized motorhome scrap both ends at once on one of the more northern Hwy 1 curves! One of the more interesting bicycle rides I have done was from Jenner north to Salt Point. The traffic was bad enough, but the wind was howling from the north. As a side wind, I had to lean me and bike way over to the left to counter the wind -- but had to careful not to fall over if a car passed and blocked the wind. Not a relaxing ride, but it was a long time ago.
