Ataskoa was a public announcement, made in the newspapers, over the radio, with flyers, posters, etc. to create a traffic jam in the hills.
On 18th September 2005, 160 cars (approximately 425 people) gathered at Intza, Navarre, on the sides of Mount Aralar. The jam started at 11am. and ended at 15pm.
