Can positively confirm the Wunnel has appropriately sized holes at each end in both directions.

The funnest part of the Wunnel was watching many cars and trucks, who had somehow failed to notice several kilometres of signage, attempting last-moment lane changes to avoid being sucked down into its gaping and hungry maw.

Also I went in the Wunnel. It was shorter than I expected. Still, it definitely worked.

Every sign tells a story.

I never drive into work, as a rule. Tomorrow I need to, because I'm going to need to get some stuff into my car from the office before Wednesday morning.

This post is me attempting to reinforce the knowledge that I need to drive to work tomorrow because I know there's a non-zero chance of this fact not surfacing in my brain until I'm already on a train.
