what's the PIN for?
It's a little joke DPS has that makes them laugh knowing people think it really does mean something. When you call and ask about it, they transfer you to the Head of the Pin department or "Pin Head". If they don't record it to play back later, they put you on speaker and discuss it like they're really checking something while they "shush" everyone sitting around listening and trying not to laugh out loud. After a while they just make up a date and hang up hoping you don't ask any questions.
It lightens up their day and makes them laugh so it's all good.
To add to this Texas secured a number of trained Asian monkeys to process the applications. These are distant relatives of the Trunk Monkey and the Opposition monkey. They work a break neck speeds but everything they do has to be rechecked by the HEAD monkey who is kin to the now late Jacko ( Michel Jackson)
120 days and still waiting - LOL!!!!!
