Best way through San Francisco South to North.....

We always carefully plan our way bypassing SF and going through Oakland then reconnecting with 101. The interstate highway signs are confusing and sometimes you won't see a sign for a long time and think you are off track. A GPS will help reassure you. Best to avoid rush hour traffic if possible.

We have enjoyed stays at the Petaluma KOA north of SF. It's a converted farm/ranch with animals to pet and a pool and stuff for kids.
