I know we have the bank where we can keep money, but was looking at the idea of being able to hide money if you have exceeded your bank limit. 

Could have a extra catch here that this could be found by other inmates, while searching certain areas.

Yes lke mabee a hidden locker or something

and with the risk of inmates opening it and getting everythng inside

Lol, so that is the same as being raided and they take from the bank as if they can open the locker and take the cash...

could bury it in the yard but then a new feature could be  digging in the yard  and u mite find peoples cash

Good idea ! but in the other hand... not...

Mufasa, come quickly! These guys will blow you away, pure gold.

i like that idea mabyee something along lines of that or lke a crime you clik on inmate name then dig yard or something

Just stop it..
