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.
