This is kind of funny.
Me and my roommate shoot guns all the time, since we can shoot in our back yard. We also both bow hunt, so we shoot our compound bows in the yard.
One day, out of boredom we set up a slingshot course in the back yard, and ran it with a timer, and it ended up being really fun. We ended up doing like 5 rematches that day.
I find it funny, since we shoot Ar-15's, pistols, shotguns and bows, you wouldn't think a slingshot would be fun, but it was a good challenge. I'd get one just for fun.
