People getting into burning grease need to have their eyes opened. Too many of the conversion sites/blogs/for profit companies are still telling people all they need to do is ask for grease at their local diner and they'll gladly give it to you because they have to pay to have it hauled off. This is, for the most part, false and the reality is that most places now get paid for their WVO. Are their exceptions? Sure, but with each day those exceptions are becoming less and less.
