Bring your kids to the winery!
Ok, maybe not. But in the off chance that you do, The New York Times had an article yesterday on Napa Valley Wineries that offer a kid friendly environment.
With a little planning, the wineries of Napa will serve the underaged. Some wineries offer coloring books, crayons and fruit juices to occupy children while their parents sip chardonnays and cabernets. Others have picnic areas, interactive displays, aerial trams or caves that capture young imaginations
There's also a list at the end of the article on Wineries in the Napa Valley that will accommodate your children should you bring them along.
