Used to think checking the site myself was overkill. That close call proved me wrong. Now I'm the guy with the binoculars too.

What about just saying "used"?

My uncle collects old trade catalogs and the numbers for a steam hammer forge were even worse. One from 1910 said a medium sized shop could use over two tons of coal in a day just to keep the steam up. It wasn't just buying the coal, you needed a team and wagons to haul it all. The whole economy had to be built around moving that much solid fuel.
