Napa's Next

Advance sign for California 37 exit from eastbound Interstate 80 in Vallejo

California 37 doesn't actually go to Napa, but it's a handy bypass around Vallejo to reach California 29, which does go to Napa. Exit numbers and reflective sheeting are indicative of the exit signs that replaced the old-style button-reflector signs. This photo was taken in May 2009.
