Actually, I have only ever driven to Mexico from Saskatchewan (Vancouver is a fairly recent place of residence for us). If you are in Oregon, my past routes will be of no use to you. However, as there are many folks that winter out down here from Washington State and Oregon, simply post your query directly on this site. A more widely used site for points south of Puerto Vallarta is Tomzap.com. The visitor comments section for the town of Barra de Navidad is a flurry of activity. Barra is less than 20 miles from La Manz.
