As I sorta expected, Ammonium Nitrate fertilizer does not appear to be available anywhere in the state. After various feed, fertilizer, and garden stores, I checked with the largest Agribusiness supplier in the state. They don’t carry it. I’m betting there are shipping restrictions about getting it out here to the islands, too. Security paranoia about the ‘other things’ it can be used for.
I’ve taken to ordering a couple cases of ‘Instant Cold Paks’ that use the stuff. I suppose if I order too many of those I will get a visit, too. 🙁
