Fascinating. For the poster who was going to watch the rest tonight -- The second episode is on tonight so don't miss it while you're watching the first one! They are running it on three consecutive nights (at least, our PBS here is).
This is a period about which I know little but the very basic highlights we all recall from school (speakeasys, gangsters, Capone, depression, repeal). It was good to get the 19th-century background to the entire prohibition movement. It was especially interesting for my husband, who is English, and who knew even less about the period. He is now a fan of Carrie Nation!
