...when you almost drive into the ditch as you check out other people's setups and automatically count how many taps they have per tree.

And when you debate whether you should say something or not to the person porcupining a huge old maple, just 'cause it's what their grandpappy or great-great grandpappy did. I'm all for respecting tradition, but some traditions are seriously outdated and often hazardous too.

For a non-maple example...I don't know anyone who now worms their workhorses using a beer bottle filled with turpentine and milk, but that's what they used to do, as recently as the 1940s and 50s!
