I just don't understand how or why the government would want to stockpile that much grease. Would it not make more sense to have a recycler come and get it on a scheduled basis?

Yeah, there is no end to government waste. How do y'all think we got almost 17 trillion in debt? It's a bad situation this country is in. Overspend on things we don't need, borrow money from China to pay that debt, print more money to pay china, raise taxes, and spend some more. 2+2=5 if you add one more.
