SPOTSYLVANIA—For Johnnie Wood, there’s no greater joy than helping people on fixed incomes who have trouble getting out of their homes. The Spotsylvania County man is willing to drive within a 25-mile radius of Fredericksburg to cut the hair of men and women who are elderly or disabled. He’s not interested in making a lot of money—he charges $10 a cut—or working full time. He’s after a different payment.
