Go/No-Go Gauge for Cave Tours

You don't want to get halfway into a tour for a cave and then find out the passageways are too small for your comfort. This entrance (at Silver Dollar City in Branson, MO) puts a cutout of the smallest passageway right at the entrance to the line for the tour. If you, your stroller, or your family members can't make it through this cutout, the tour is not for you. 

This type of gauge is useful in both manufacturing and in real life!
