Maybe you found the final resting place of the Mystery Machine!
Awesome! I just have to keep digging! And I'll need lots of Scooby snacks.
In reference to the location, I'm told my property used to be a farm. There is a pipe sticking out of our yard that we thought was a property marker, but turned out the be what was left of an old hand-pump. I dug up four custom made horseshoes as well - not the pot-metal ones that come with the game from the store, but four real ones, each one unique and obviously fitted.
I definitely need to keep digging - maybe I'll find the rest of the van!
Thanks so much guys, I really appreciate the 'sleuthing'. Guess this is one we can't blame on the 'darn kids'.
