Thanks to Arbor Heights Elementary School teacher Mark Ahlness for sharing that video of his third-graders (who can be found online at roomtwelve.com), decorating “Earth Day” grocery bags and then delivering them to the Roxbury Safeway. Ahlness says Arbor Heights kids decorated more than 300 bags this year, the 16th consecutive year of their Earth Day partnership with Safeway on this project, and the 15th anniversary of the Earth Day Groceries Project, which Mark notes began at Arbor Heights. If you shop at that store today, you’ll likely get one of these bags. Meantime, today is the day the five local students on “An Inconvenient Ride” are expected back in Seattle, with the homecoming festivities taking them downtown tonight for the “Global to Local” benefit at Benaroya Hall. 8:11 AM UPDATE: Just got word from the Southwest Precinct that the Inconvenient Ride-rs may have up to 200 bicyclists accompanying them on their last leg, and the precinct wants to alert you to their route, for safety’s sake – will post more on that a little bit later this morning.
