So, we have a bunch of gun nuts and nerds that read this
I was out today trying to mark a property line using some string. I had one pin on one end and another on the other. Running the string proved difficult due to trees, slopes, brush and all manner of other things in the way. So, I had an idea! A string gun! Put in a roll of string (this style), attach the string to the gun and launch the roll. Any idea the best way to do that?
