The Orange Jacket
On a daily basis it is very common for Larry Chadwick to be out working the land in some way. With cell phone signals practically non-existent in his area, there is no way to call him if someone comes over (which is also common), or if he is needed back at the house. And so, there is the orange jacket. It's a simple enough signal, able to be seen hundreds of yards away, and with one message: come back to the house. I've seen it in use. And it works.
