I buried my water lines a couple of years ago, so now I only have short hoses running from the hydrants to the tanks. I remove the ends of the hoses from the hydrants and drain the hoses on nights when it is going to freeze.
For ten years prior to that, I had two 100 ft. hoses. Every day (when it was going to freeze), after filling the tanks, I'd leave the hoses stretched out and drain them by doing over-head, hand-to-hand lifts down the length of the hoses. It really didn't take too long but my shoulders got a really good workout doing it.
