Conquest: Back and Forth
(That was an attempted reference to Blackadder: Back And Forth, where Edmund jumps back and forth through time, because...oh, never mind.)
I became aware of this show by accident several weeks ago, catching only the last minute or two of an episode in which "unusual" weapons, specifically designed to combat plate mail, were apparently covered. The one I saw -- or didn't see, as I said -- may have been the last scheduled repeat of that episode; in any case I have not seen it come around again.
Since missing that one, I have seen at least three episodes (on the tournament, the bow, the axe...if I've seen a fourth one I cannot remember it at the moment). I wish I'd taped these, and might start taping the ones that are left, in hopes the earlier ones will eventually repeat again.
Apparently the show also covers more modern activities, like rodeo and demolition derby, which I am really not interested in seeing, and I can't always tell ahead of time which episode will be shown. (Ah, now that Back and Forth thing makes a tiny bit of sense.)
