FIT is a great stool test because it only looks for a specific type of blood related to signs of colon. cancer. Other types of blood that may be in your digestive system from your diet (red meat) would. not result in a positive FIT. This allows for the test to have a greater level of specificity for colon.
I drew the route and the interchanges of the proposed Outer Beltway on this copy of the 1980 MDOT SHA state road map. The dashed blue line is the Outer Beltway route, and the small circles signify the interchanges. Click for large image (567K). This proposed route had 37.1 miles in Virginia and 64.7 miles in Maryland, for a total of 101.8 miles. It had 13 interchanges in Virginia and 31 interchanges in Maryland, for a total of 44 interchanges. The proposed route had 6 lanes (3 lanes each way) throughout.

Reputation: 33. Ft. Meade is only 25-30 miles from DC, but depending on which route you take, it could be a hellish commute. If you're coming from DC, I would avoid the Beltway. Regardless of which loop you're in, the Beltway is unpredictable and often jammed during rush hours.
