Analysis of information sources in references of the Wikipedia article "Vortex I" in English language version.
Oregon's 1970 Vortex gathering near Estacada may have been the only government-sponsored festival of sex, drugs and rock-n-roll in U.S. history. About 100,000 people attended the week-long event, remembered by some for its spirit of community. Police and the National Guard were on hand for Vortex, but they were told to look the other way as revelers broke loose during Oregon's version of Woodstock. Although the event had that gathering-of-tribes feel, it also drew some non-counter culture Vortex "tourists." The festival was held in order to alleviate potential demonstrations during a proposed visit by President Richard Nixon.
