Funny thing happened to me a couple weeks ago...
I went to fill up the horse water tank, and my hydrant was froze. I built a fire around thie pipe and opened it up, and a few minutes later, the water started running. I filled up the tank, turned off the water, and water started coming out of my shut off valve buried next to the house. I went to the rental shop to price a mini hoe or a back hoe, ran into a buddy and told him my story. I have to note, I did not ask for help. I had to go out of town for the plumbing fittings and was gonna tackle the project the next morning. When I got home, there was my buddy with his back hoe, a giant hole in the ground and another buddy already in the hole fixing my pipe. Those are the kind of guys you need to keep around. I fueled up the back hoe and offered money, but all they took was dinner and beer. I guarantee if I hear of them needing a hand, whatever I am doing can wait. Granted, this happened on a Saturday, and maybe they didn't have a whole lot going on, but they still took their time to come save my butt.
We've all been burned. You go out of your way to help, but when you need a hand, there's nobody around.
