Seemed like they always had them at Stuckey's in the gift shop (which we'd always stop at on family vacations).
close friends of my mom's lived in Asheville, SC. We visited them every couple years. Every time the husband had something interesting for me to keep me occupied while the grown ups talked. One year it was the gee-haw wimmy diddle, one year it was a bb-gun w/ 2-liter bottles hung in the trees for targets.... so mine has a special connection for me to Appalachia... that was ~30 yrs ago so it's getting kinda worn.
need to make another sometime!
fun trying to show my kids now to make it go and change directions.
