Isaac is a great guide. I indicated that I wanted to see a specific winery (Kendall Jackson), he organized it and found an interesting winery (Paradise Ridge) close by to visit. He was well prepared, although he never went to this place before, we found a typical local sausage place for lunch (not haute cuisine, but great tasting and typical for the rural USA). No regrets!
TOUR GUIDE RESPONSE: Edwin, you were a pleasure to spend the day with. I shared the Kendall Jackson with friends that night and we all could not believe how delicious it was. Thank you for a great day!
