This photo was originally labeled U7 Mystery Shot, which I retorted in Seattle lingo U7 would denote an Unlimited Hydroplane...
‘CARPETS:
Here is the mysterious oo7 pic. A vacant lot next to Dallara Automobili where some excavation has begun... Is this the new location for Andretti Autosport?? Hmm, we'll see...
Obviously I have NO idea towards the validity of this, as I can only surmise this is a guess – so you make the call!
UPDATE
With the announcement that SFHR will take up occupancy on Main St in fall of 2012, I’m guessing this is perhaps the property site, eh?
