Sweet! The Ferry Building is a classic SF spot. Definitely share those pictures, it's always packed but has its charm, right? If you got some of the Embarcadero I'd love to see those too, I run there all the time and love seeing it from different perspectives.
As someone who runs the Embarcadero at dawn, can confirm the layer tactic is a must. But be careful with too many bulky layers. You want to be able to move freely, so look for compact, high-quality materials that give warmth without the puffiness.
