caboose

I walked over to the caboose to see if I could find a geocache. I know that it is along the centre beam by the spring mount. Now I figured out what the centre beam is, but the spring mount? And it's a lot of undercarriage for me to feel around all the sneaky corners. So I thought that I would google "spring mount" and try to find it another time. And the horse? The shortcut to the caboose is through the horse barn at the exhibition grounds. I stopped to talk to the horses on my way through. They were bored silly and welcomed any interchange, even from me.
