We love to take out-of-town guests to wine country. We've been to Napa a few times, but when Kristina visited, we decided to check out Sonoma instead. It was definitely less touristy than the Napa area and the vineyards and restaurants are fantastic.
Fun fact: the Sonoma Plaza is the largest in California! The town square is so lovely and next time we're definitely bringing along a picnic lunch.
here and here. I may or may not have asked Kristina to take a picture of my ring... :)
