Ok. I need to get rid of about 50 banker boxes solid full of paper.  What would be the quickest, most economical way to permanently dispose of this material?  I need someone who can relate first-hand experience with a solution that worked well.  

I have occasionally encountered shredding trucks parked in the local bank parking lot.  Can these type of shredders chew up entire bankers boxes one at a time?

What works for you?
