What's in my backyard?!!!

Coming back from the beach this morning, we turned into our neighborhood and were confronted with this huge hot air balloon behind the houses. It was actually in a an adjacent vacant lot but gave the appearance of being in the yard. A local real estate office ran a promotion to attract potential customers and they were giving free rides in the balloon. YES, the balloon was tethered to the ground so it was not a real, off-into-the clouds flight - still a thrill, if you've not experienced it before.
