I really thought this was an asteroid.
Brittany thought it was a crate found at the bottom of the sea (hint: she's a big fan of Pirates of the Carribean).
It's really a Tabernacle.
I thought this was home to one of those "ride simulator" thingies.
Brittany thought it was a giant tent.
It's really St. Malachy Church in Burlington, Massachusetts, the church that houses the above Tabernacle.
Hat tip to Gerald, who passed their Tabernacle for a Borg ship.
