so i am a college student who has no car, and go to school in Emmitsburg which is about 15-20 mins from frederick MD. Anyway, i was noticing there is no train or bus service at night to DC, only god knows why, i think its stupid!, but anyway, there is not, so i was wondering how might i be able to get to Shady Grove metro using public transport or a cab, from Emmitsburg or i guess i can do Frederick,(maybe)?? anyone know the cost and how I would do it??? please help! thanks!
