I am a 22 year old young woman looking at Ohio State for Grad School. What can you tell me about Columbus? Is there much to do? A lively downtown? (I am not a social butterfly- I go to work, school, gym and study, but its always nice to study downtown at a cafe or walk around a hoppin' downtown) . How are the gyms? How are the grocery stores? Do Farmer's markets exist? Where are good neighborhoods too live? (Lofts downtown? cute small houses in neighborhoods relative to downtown? or any other fun cultural spots?)
