I count cranes

I look for old trolly tracks.

I notice last name's on buildings. I see about the families who built them.

I locate equipment manufacturer's plates and inspect them with my fingers.

I time how long it takes for a coffee and muffin to hit the counter.

I browse bid opportunities and public records.

I'm probably asking "Is there a factory tour?"

I hear conversations in diner booths and hardware stores. I say "Hey, couldn't help but hear..."

I snoop around auctions, surplus, marketplaces, and warehouses.

I check where a website gets their traffic. I notice when a sign changes. I google the contractor who was awarded the job...Small shifts and signals.

I pay attention. See who's buying and who's selling.

I follow the fisherman who go where the fish are. I see who's catching what.
