Funny story, as a retired anesthesia doc I assumed I would have no trouble getting ether to mix my own diesel. Wrong!!!! MD/DEA license or not the company would not sell me any ether. The comment was (correctly) that 1)ether has not been used in the US as anesthesia for many years 2) I do not possess a chemist's license which would have gotten me ether and a whole host of other things I imagine 3) What could a doctor possibly want with ether? My explanation of home made model diesel fuel did not convince anyone. Wonder if I am on yet another list in D.C. because of this query.
