I've lived in Howard Co., Laurel since 1989. There is sporadic crime here but it is usually minor. You can check the Howard Co. Police Website. I either drive down 29 to Silver Spring and then take 16th St. to DC. The traffic is usually fine until Four Corners where it slows, then it picks up again. But there are great commuter buses which are cheaper than driving, gas, etc. Check out
www.mtamaryland.com. I take the bus about 2-3 days/week. Currently costs $38.25 for 10 one way trips to and from DC. It's cheaper if you get off in Silver Spring (at the Metro).
