I've seen three. The giant baseball bat in Louisville, the Ben & Jerry's ice cream graveyard in Vermont, and of course the Cadillac Ranch outside Amarillo. I can't believe they left out the giant Superman statue in Metropolis, Illinois.
The amazon link didn't work. I've about decided the cotton geocache event shirt just isn't suitable for Texas summer caching. I've started wearing dri-fit running or even golf polo shirts, just to get some breathe-ability in the sweltering humidity, and would be interested in picking up some more.
I found some wonderfully scenic caches in Oregon. Of course, I was going for specific ones to fill in my Jasmer calendar, but there something to be said for driving and hiking for 18 hours and logging 10 finds. Awesome part of the country!
The first ticket I ever got from a Houston cop was for speeding on the feeder road just after exiting the Gulf freeway. They love to radar folks coming off the exit ramp to try to catch anyone going over 45 mph.
Do they show on the map? I think I've run into this same issue with the 64s and the Montana. If I was planning a long road trip and tried to start the first leg by routing to a cache several hundred miles away, I had to find it on the map because searching by name wouldn't pull it up.
It would seem that on devices that accept the GGZ file format and can have hundreds of thousands of caches loaded, there needs to be a limit to the search-by-name function to keep from slowing the device to a crawl.
