It was raining and the warm air was thick with hungry mosquitoes but the crew assigned to start construction on the bog bridge didn't take notice. The large stump blocking the path would go. The muck in the bog would be removed. The sill beam had to be perfectly level. And the stringers must align neatly. This punchion boardwalk bridge over a certain bog on the Florida National Scenic Trail would be just right. No question about it.
