If Napa County is wine country and Calaveras County is frog-jumping territory, where does that leave a place like Solano? Trying to catch up, perhaps.Thirty years ago Napa County was where Solano is today, says Solano County Supervisor Mike Reagan. In 1992, Napa brought in $361 million in tourism revenue, and with $319 million, Solano wasn’t far behind. Fast-forward to 2006: Napa brought in almost $890 million, but Solano’s revenue only rose to $554 million.
