Close is a relative term. There's a vineyard within 20 miles of my home. Also, the Santa Barbara area has numerous vineyards and tasting rooms and is less than two hours away. When I have visitors staying a few days we sometimes plan a day trip there. We take the train up and spend the day wandering the shops, missions, beaches, restaurants and tasting rooms. It's a charming area.
Do you have favorite things to do or places to take out of town company?
