Vacaville, named for its founder, Juan Manual Vaca, grew up next to what has become a major highway to Sacramento and points north. It became famous for its Nut Tree Restaurant, which for decades offered travelers the produce of this fertile fruit-growing region. Now the modern highway bypasses VacavilleA[a¬a[s historic downtown, leaving it to be enjoyed by the growing population of greater Vaca Valley. Even though the modern city has grown out to engulf that new highway and an ever more diversified economy continues to thrive, old Vacaville still feels and looks like a small town of another era. Unscathed by earthquake since 1892, enlightened city officials have not only preserved much of the original downtown but have added a A[a¬ACreekwalkA[a¬A that gives an air of quiet greenery.
