With her children grown and husband nearing retirement, Amy Reynolds was ready to leave behind snowy Flagstaff, Ariz., to travel but she wasn't ready to give up her nursing career. She didn't have to. For the past three years, Reynolds, 55, has been a travel nurse — working for about three months at a time at hospitals in California, Washington, Texas and Idaho, among other states. Her husband accompanies her on the assignments. "It's been wonderful," she said in May after starting a stint in Sacramento. "It's given us a chance to try out other parts of the country."
