Well, not quite two years out of date -- fourteen months, maybe, but not two years. Whatever, all I can do is offer the link -- it's up to others to freshen it. I did read somewhere a newer report -- but don't remember where that was.
Sorry I don't have all the information. Up here we don't have salt, except on the roads. We do have frozen lakes, though -- they look a lot like the Salt, just colder.
