Over 150 participants took advantage of the stellar weather and an adventurous spirit of the 2011 Alki Street Scramble on March 19.

Adventurers started out at Alki Beach, near the bathhouse, and had either 90 minutes or three hours to set out on a West Seattle scavenger hunt, self-propelled by foot or bike.

Participants were given a map of West Seattle with 30 checkpoints to visit, one as far south as Lincoln Park, and had a half hour to map out there route before the Scramble began at 10 a.m.

Team sizes ranged from solo to full families and the level of competition ranged from a serious adventure armed with GPS units to a leisurely walk with a purpose.

According to event organizer Eric, about two-thirds of the participants are competitive scramblers who participate in several of the 10 events held each year.

Each checkpoint corresponded with a multiple choice question on the back of the map to ensure people actually visited the site.

Street Scramble events happen throughout Seattle. For more information, visit http://www.streetscramble.com/.
