LOL. If that was a cell site, I never saw one that had writing on the ground...Sadly enough like Rich said, that site use to be the Bellevue Airport until property taxes got to be too much (Thanks Bellevue!). By the early 1970s, it was a very busy little airport, with a total of 51,000 takeoffs & landings per year. They stopped operations in 1980. Ever wounder why the street poles on the off ramp of I-90 and 148th Ave SE were painted red and white? In the Google site, you can even see part of the old runway. If you go into that Dairy Queen, they have pic up of what that area use to be like and/or look at the link.
