I'm from North Bay- Sonoma Valley. But, there are doodle romps closer to you, I believe. Kiley at Harmony Labradoodles and I think California Labradoodles put on a doodle romp about once a year. You could contact them. I know that there's a doodle romp in Davis every couple of months. Plus, there's a much bigger doodle romp in Huntington Beach (which I know is pretty far) but they have them quite frequently.
We live in Los Gatos. I don't know of any doodle romps. If you learn of any let me know. Abbey is almost 6 months old and weighs about 21 lbs. She does romp with a couple of other doodles now and then.
when I last went to check idog.biz, it said they were beginning to organize doodle romps for the romp around the world. That would probably be your best bet to meet people and then form romps amounst yourselves.
