Give me a museum and I'll fill it. (Picasso) Give me a forum ...
Each mom on our city street had her own personalized yodel, and they'd do that from their back porch at dinner time to summon us home. My Mom's was a very high pitched "Ooo-hoo.... ooohoo ooohoo ooohoo!" Our friends' mothers each had their own different yodel to call their kids in. One of them had a bell.
My mom had a three-tone whistle. My dad w*rked most nights until near dark on the "back 40" as we used to call it. It was actually an acre, but he raised vegetables for us and ornamentals for the local markets. When dinner was ready, mom would give her whistle though a make-shift PA system on the back porch. When I was playing (and she wanted me to come home) I could hear her amplified whistle a block and a half away. Hadn't thought about that whistle in many years. Thanks W2R and Thanks street!
