My seven year old Granddaughter was visiting and found a hairy caterpillar on the deck one morning and proudly announced she had found a Callerpitter. We tried without success to get her to say Caterpillar to no avail.
Sixteen years later she still says Callerpitter. The new coach has a Cat C-7 engine and one day the bright light came on and a graphics desigh company made a decal of an Inchworm with the name Callerpittar under it.
It is on the righr rear engine cover. If you see it "Honk on the way by" .
