As we departed after breakfast at about 10:30 AM, we were expecting fair weather in the morning, with the possibility of thundershowers later in the day. The Mt. Vernon Trail runs through Alexandria, so we got on it right away. We had traveled on it yesterday from Mount Vernon to Alexandria, but we were so miserable from the terrible weather that we failed to appreciate how nice it is. We crossed over into the District of Columbia and spent some time taking pictures of the monuments, the White House, and the Capitol. We walked the tandem most of the time because of the large crowds, even though some of the routes in that part of DC are listed as bike routes. We managed to stay on bike routes as we departed DC and crossed over into Maryland, but it was rush hour by that time. Many of the roads had wide, paved shoulders; but needless to say, it was fairly nerve-wracking as we challenged the cars and trucks for space on those narrow roads with no shoulders. We finally came to the bike path that runs around Baltimore Washington International Airport and were able to feel much safer on the last leg of our trip to Linthicum. However, the weather had deteriorated, and the ugly black clouds told us we were in for some more rain. Just as we arrived at our final destination at 7:00 PM, the rain came. 
We are staying at the home of Butch and Barb Young, college classmates of Susan and good friends. Susan, a native Marylander, had been anticipating going out to have crab cakes when we arrived in Maryland, so that was the plan. It was so late that we kept on our bike clothes when we went to the restaurant. It's a casual place, and my tight shorts did not draw as much attention as they did in West Texas, but there were some stares. After an excellent meal, we sat around talking, probably for too long since Barb has to get up and teach tomorrow, her 48th year as a high school English teacher.
