Crack for clunkers?

God knows I haven't always been the best son, but at least I've never done anything like this to my dad:

The Fresno County Sheriff's Office said deputies responded to the home of a 74-year-old man just after 4 a.m. Wednesday and the man told them his 39-year-old son had taken his Lincoln, The Fresno (Calif.) Bee reported Thursday.

Sheriff's spokesman Chris Curtice said the 39-year-old returned while deputies were still at the house and investigators learned he had traded the car for about $50 worth of crack cocaine in downtown Fresno.

I don't know much about crack, but I would think you could get more than fifty bucks worth for a Lincoln. I guess it's a buyer's market.
