I thought the first geocache of the day, "Light Cache", was in a neat location. It's between the second and third floors of a lighthouse. Of course, this lighthouse is far from the sea because it's a display lighthouse at a store that sells sheds, play equipment, and other things you can place in your yard. Ordinarily, I'd say that I can't imagine who would buy that, except that I've already seen a lighthouse in someone's front yard.
The other thing I thought was neat is a series of geocaches by Trison78 where all the caches are various plastic animals and the cache names are scientific names for those animals. So "ANURA" was a frog geocache. If you don't recognize the order or genus then it'll be a surprise. I may have to brush up on taxonomy; I knew that "APIS" was a bee but didn't connect "CAELIFERA" to grasshopper. I'm waiting for a "VULPES" cache though. :)
