A city on the east coast of Maryland that is very popular because of its beach and boardwalk. Its population increases threefold during the summer months as people swarm to hotels along Coastal Highway. It is also the beginning of Route 50, which ends up in Sacramento, CA.
If you plan on staying in OC, do stay on Coastal Highway, and all the fun stuff (like the boardwalk, the sand artists, the kite shop) are towards the lower-numbered streets.
