Now that global warming is getting realler and we're running out of oil, might be a good time to close the speedway. We really don't have the luxury of pouring gasoline down the drain for our entertainment - polluting the air. It would make a great place for a City farm/orchard. Let's get real about our problems and stop the status quo thinking that keeps our problems growing beyond fixing. Close the speedway already!!!! And, vis the airport? I'd love to see the National Guard stop flyng sorties over Portland. a) it's only a matter of time before a plane crashes in a neighborhood - the fumes from the airplanes really aren't adding to anyones' health and the threat from an attack by fighter planes from ... ??? not sure why we need to be flying sorties every week around a major metropolitan area. So, yes. That's one airport that could be closed in my humble opinion!!!
