I want to suggest that one of the most important/fun parts to the sport of slingshot shooting is giving slingshots away.
It's been a number of years since I've written about this but I like to think it should be talked about from time to time. I just finished an overly long post on Bands Breaking which touched on it and got me thinking.
By my estimate i have probably given away 100 or so slingshots. The circumstances vary widely from groups to friends to strangers and sometimes homeless but each case helps in its own way to "move the needle" towards the advancement of the sport.
One of the real pleasures of the sport has been making and experimenting with slingshots made in different shapes and materials - some of which have been pretty strange. The end result though is that I end up with slingshots that are cool but rarely used. I also shoot a lot and in a lot of different places and so have struck up many, many conversations that have resulted in my grabbing a spare out of the truck along with a handful of, usually, 5/16 balls and given them as a surprise gift. It seems like a lot of conversations (I'm a dentist) head in that way too and it's been fun through the years to grab a slingshot out of the office and hand one off. In all of the years that I have shot I have never been criticized or complained about nor had any trouble from anyone.
In my world it sure beats filling a drawer with slingshots that I never or rarely use.
If you haven't done it before try it. You might open up a a whole new chapter in your enjoyment of the sport!
