Remember that letter you wrote to former U.S. Representative Tom Tancredo? It's probably gone. Tancredo got quite a lot of use from the Powershred, discarding years' worth of documents from his Washington, D.C. office, according to Politico. Sure, Tancredo might have found a Colorado university to "pretend" it was interested in his documents. But he says the transportation costs alone made shredding the best alternative.
