I know in my state NA beer is still considered to be beer. Have to be 21 to purchase, need a liquor license to sell it, etc.

As I recall it’s because the definition of beer in the state statute defines beer as a fermented drink with certain criteria like wheat, barley, hops, etc. as ingredients, and alcohol content not being one of the criteria.

It actually meant a local sober bar (a bar-like place that only serves NA drinks) had to go through the hassle and expense of getting a liquor license.

I think they used to wax the cardboard. Maybe they still do?

Weather forecasting is actually really important for military operations. Consider weather advisories for aircraft, for example. Or planning an offensive on a clear day.

That said I don’t know if this place was doing climate science or weather forecasting (or both).
