We don't know where they all are, so let's find as many of them as possible! For those of you who are not near one of them, you can also log a sculpture (not a photo, painting or other two-dimensional work) of another piece of fire equipment that is "on a grand scale." Do not include statues that include persons using the equipement.
Log the coordinates along with the city, state, or wherever that you found the sculpture. Post a photo of you and your GPS in front of the sculpture. Include any information you find about it as well. If you're caching alone, have your GPS and some other item in the photo to give an idea of the size of the sculpture.
The normal rules of locationless caches apply: one log per person, one log per sculpture, no vacation or internet photos, etc.
