I had contacted a number of tour companies, but David's response was timely and engaging. We talked about what I wanted on the tour. I had three specific wineries selected, and when he heard them, he knew we were looking for great cabs. He made all the arrangements, and we exchanged emails a couple of days ahead of the tour date. Susan picked us up right on time and we started on an exceptional 8-hour wine tour. We visited our selected wineries, had a great lunch at a winery selected by Susan, and visited another of Susan's recommendations. While driving in the crazy Saturday traffic, it was as if we were traveling with family, touching not only on Napa, but children and grandchildren. However, at the destination, everything was highly professional. Susan's insights on the valley, the vineyards, and wineries were so informative. We also discussed restaurants, places to stay on future visits, and more. While on our tour, David called to see how things were going, as he was traveling to conduct another tour. David and Susan Locke exceeded all our expectations. My wife said she could not imagine a better day in Napa, and I heartily agree.
