Here’s another Portland area mystery – what the heck is that? I have a full set of pic on Flickr – click here!

I’ve tried Facebook, Twitter, LiveJournal, craigslist, everything I can think of to find out if anyone in the area has any idea what this is. One lead is a user on Flickr who claimed his dad built and launched it years ago. I tried to contact the user for more details, but no reply.

Can anyone help??
