I've also never seen a real jail cell, so it was really interesting for me too.
This is in back of the police car. I have been in the back of a police car before. My friend & I were driving on the highway & a metal piece fell off of a truck & my friend hit it & we got a big hole in our tire. Her bright idea was to walk on the highway to the next exit. A trucker called the police or walkie talkied it in (Do truckers still walkie talkie things? haha) that we were walking along the highway, so a cop came & drove us back to our car & lectured us on "Never walking on the highway".
