Why wouldn't you want an almost life size Tyrannosaurus Rex for your backyard? My daughter would think I was the best mom ever if I let her put a huge dinosaur statue in our non-existent yard. My husband would be kind of excited, too. My neighbours - all of those over the age of fifteen, anyway - probably a little less so.
But even if they didn't like it, owning an 11 foot tall dino statue would all but guarantee that you would be the coolest parent on the block (unless someone has an in ground pool, in which case you may be out of luck. That said, this almost certainly trumps an above ground pool, and also a trampoline.)
