Jail is a little scary, but depending on why he is there, its good that it's scary. If you can go see him, go see him. It's the middle of the week, so he will most likely be released today. I would find out what happened. Jail isn't the same as prison. Although it's not a good place, the county jail isn't going to be the cause of any physical damage (Don't tell him I said that.) Let him be scared, and let it sink in that not obeying laws puts you in awful places. Going to see him doesn't mean you bail him out. As I said, he will most likely be released today anyway. It just depends on the charge.
