Flew to Centralia after work.
These are 2 operational Seattle "Supertoilets" now located at South Sound Speedway. City of Seattle bought these 5 or so years ago for 1 million each and they didn't work out. Southsound speedway recently bought them off Ebay for about $12,549.00 for all five. What a deal!
Here are the other 3.
Chehalis / Centralia Airport
Here is an Ercoupe on short final at Olympia.
