We have the scenery. We have the activities. We’re even about to have lodging. Is “sustainable tourism” another way to boost West Seattle’s economy? (And what constitutes “sustainable tourism,” anyway?) That topic’s on the table for tomorrow night’s Sustainable West Seattle community forum, and you are invited both to come hear about the idea and to share your thoughts. Guests include Greg Whittaker of Alki Kayak Tours and Mountain to Sound Outfitters, Patti Mullen of the West Seattle Chamber of Commerce, and Heidi Siegelbaum and Steve Gersman of Calyx Sustainable Tourism – tomorrow, 7 pm, Senior Center of West Seattle (California/Oregon)
