I've been laid up waiting fusion surgery. I've been watching too much TV as a result, so I'm watching Bonanza and in one scene Joe Cartwright is
chatting with the local blacksmith. In the background of the blacksmith shop are two crawler sprockets. I guess crawlers are much older
technology than I previously thought? I like to watch for things that aren't "period" as I waste time watching TV.
