It's a guy in western Washington State who apparently just started selling on Amazon fairly recently.
https://www.amazon.com/Shepherd-Sling-Shot-Rock-Black/dp/B07TZWTZ38I was hoping he would have already introduced himself here at some point in the past, but if not, I hope he does soon. We need more enterprising sling-makers to talk to each other and help each other out instead of seeing the world as a zero-sum game of competitive selling. (That goes for all of you other lurkers too!)
The only person in the last several years who it might be is MightyHunter, but he never posted any sling pics. PalouseSling is from the wrong side of Washington State, so unless he moved to the coast, I don't think it's him. Lots of other people give introductions without saying where they are from though.
Come on folks... Please introduce yourselves! You might even sell a few slings to us forum members!
