Northern California. If you choose to fly you can do so via a 45-minute flight to Phoenix, AZ. We drive to Tucson, AZ from Hermosillo in 4 hours. - Aug 2015
Our home base is New England. We normally fly into Phoenix or Tucson and then drive down to Hermosillo. The drive is about 2.5 hours from the border crossing in Nogales. Flights in and out of Hermosillo are prohibitively expensive, although they have just added a new American flight to Dallas, which may help. - Apr 2013
Washington, DC. Travel by air with 1-2 connections is approximately 6-10 hours, depending on the route. - Dec 2009
