Roadside attractions like The Mystery Hole used to define family vacations, even if you were like me and now only remember them as the places your father refused to stop. Now that we're in the front seat. I make it a point to say "yes" to number of classic tourist attractions remaining. The Mystery Hole is one of those that made us glad we did. From the crap-stuffed gift-shop entrance to the "hole" itself, it's all cheesy goodness. Even our kid appreciated it. Cheap Grizwold's would love this!
