DeLorme Easter Eggs

While trolling through the DeLorme gazetteer for the state of Washington, I noticed something strange. I was looking at the possible hiking opporunities north of Mt. Saint Helens, when I happened upon a symbol that didn't occur in the legend at the front of the atlas.
It looked to me like a very furry person with mucho oversized bare feet. I thought to myself, Hmmm, Bigfoot? (actually, in truth he looks more like Captain Caveman).

I did a google on this and came up with this site. It appears that there is some sort of goofy erroneous picture in every atlas that DeLorme makes. In Oregon it's a covered wagon. In Northern California it's a wine bottle pouring into a glass. In Idaho it's a picture of Evel Knievel in his rocket car jumping over the snake river. In New Mexico there's an alien head down near Roswell. These things look just like the symbols for fish or boat launch or trailhead or something like that, so they're hard to see.
I also can't vouch for the older atlases, as this one was published in the last couple of years.
Have fun looking for them.
