OMG yes. The junk food! hahaha.
That is pretty much all those guys can buy in the county jails around here (in WA State) - that and soap, razors and stuff. Rozied, please do yourself a huge favor and check with the jail before you send him any money. Don't get taken. ;-)
I'm not sure how long your son is going to have to serve, but in order to get out of the county system and into the State system, you must be sentenced for more than a year and one day. Most prisoners prefer the state system and will actually request longer sentences just because they can wear what they want in there. In the county system they usually don't get a choice in clothes...
This makes the shoe story sound even more fishy to me...
