Weather does not look promising, but here is a route just in case. Another twisty turny tour from the Rev. Len from Cotati Vets to Petaluma, with a stop downtown at the venue of your choice. (The version below goes to River Front Cafe, since that seems to be the favorite.)

AB pace, but faster riders welcome. Meet at 10am and roll after introductions.
