OMFG we can take our full-size bikes on MARC trains! This is so exciting. Ok, it's only on weekends, and only on the Penn Line, and only at certain times, but as bicyclists, we're used to taking what we can get, assuming we ever get anything at all. And this is a very, very good thing. D.C. has awesome riding opportunities, from its buffered bike lanes on city streets to its trails—out to Mount Vernon, along the old Washington & Old Dominion railroad line, the Chesapeake & Ohio towpath all the way out to Cumberland, Maryland—the list goes on and on. Before this weekend, you had to drive your bike down there—totally defeats the purpose—or be one of the lucky few with a fancy folding bike. No more!
There's tons of good biking in Baltimore, too, and now D.C. folks can avail themselves of our area trails out by the airport—the light rail has let you take bikes on for a long time—and through the city and its parks. Welcome, D.C. people, to the Greatest City in America.
