Visiting the subway:
-Do not enter the subway illegally! You can get in a lot of trouble for this
-CincinnatiAdvanced hosted the tour I went on, but I think there are a few other organizations.
-It took me over a year to get tickets. Sign up on the waiting list now.

-Bring a good flashlight!
-If you plan to take pictures, use a good external flash. I didnt do this, I just used my digital camera's flash.
As you can see in the images, it didnt turn out too well toward far distances
-The tunnel isnt that dirty, but wear some old shoes and jeans
-When your in the station, dont fall off on to the track! The drop off is 4-6ft so you would break a few bones!

-I have heard it was hunted. It was a little creepy down there and fairly dangerous because there is
drop offs to the track and no light but I saw nothing out of the ordinary. And relax those "lights" are just
other people's flashlight.
