What to Wear  
With weather as variable as it is in San Francisco Bay we recommend the following: 
Jacket - heavy  OR 
Jacket - windbreaker AND polarfleece 
Hat (one that will not come off easily) 
Something to cover your ears (jacket hood, scarf, ear muffs, etc.) 
Rubber soled shoes  - flat with a good grip 
Always bring an extra jacket, sweater, sweatshirt, polar fleece pullover, etc., because if you do not have it you may wish you did. Remember, you can always take it off, but if you donít bring it you canít. 
You may wish to bring binoculars or a camera along.
