Globe-roaming pubcaster Rick Steves has donated $1 million to his hometown arts center — the amount he has saved in tax breaks since President Clinton left office, he said in a press release. “I see it as a civic duty for businessmen like me, who’ve directly benefited from our vibrant communities, to do our fair share,” Steves said. The money goes to support and expand the Edmonds Center for the Arts‘ performances and community programs. A portion also will underwrite all facility costs for the next decade for the Edmonds’ Cascade Symphony Orchestra. Steves also said that to celebrate the donation, he will perform “Rick Steves’ Europe: A Symphonic Journey” with the Cascade Symphony Orchestra on Oct. 23 and 24 at the center, which will be filmed for a pubTV special.
