Barona is my second favorite course, behind Torrey Pines South, in San Diego county. It is a great course, with very fast and undulating greens. The Nationwide Tour Championship was held at Barona in 2007. Go to Barona's website, they have a course tour that will show you around. They will treat you nice at Barona. The Casino and Hotel are also very nice, you will like it there as well.
If you have any more specific questions, please feel free to ask, I'll be more than happy to help, Don
