Rodeo Time

Completely off topic, but here goes anyway. Every year at this time, since 1932, the Houston Livestock Show and Rodeo is staged. It's a really big deal here. The whole city "goes Texan" (although most probably wouldn't know which end of a horse the manure comes from). I was in a shop this evening and noticed a window display in an "old west" theme, with boots, spurs, lasso, etc. Right in the middle was a model of a trébuchet. I didn't know the cowboys and/or Indians used Middle Age siege weapons.

Siege of Petersburg during the Civil War? But I have my doubts .....
