Being near the Mississippi we get them in spades. Our local park’s exit is a short but steep incline. The park gets alot of cruisers because it’s set up with a loop and has a bar at one end of it.
One nite a I saw a biker, who thought he was cool, trying to gun it out of the park, forgetting about the mayflies. Laid the bike right over. I laughed for a long time on that one.
The BNSF has double and single lines running thru that park before they cross the nearby swing span bridge. The mayflies have been so think they’ve had a hard time stopping trains some years - damn scary I’m sure when the bridge is open for a barge.
My wife’s flying home from Minneapolis-St Paul tomorrow. I wonder if there could be any impact on take-off or landing. Her two stops before Tulsa are Chicago Midway and St Louis.
