Am i doing anything illegal or would get in trouble for - Prison?

Just continue to p by on your way to work. Getting out of the car and walking close to get a look could land you in some trouble. It is NOT public property. You could be arrested for tresping. If you are interested in corrections and correctional facilities, you could go to the library and get a book out or go on line and do a search. Do not tresp on government property.
