We were supposed to go on a tour of Muir Woods and Sonoma Valley. Unfortunately, our booking coincided with the first day of the government shutdown. However, instead of Muir Woods the tours combined Sonoma Valley and Napa Valley (the Sonoma Pinot Noirs are great!). The drive was great and our guide Mitch was informative, funny and engaging. The tour was a great balance of being a group and also allowing times to go off on our own (eg. lunch). There was no pushy sales pitch and it felt like a great day trip with 'friends'. Would highly recommend!!
