It’s Follow-Up Friday: Parking Lot edition!

Welcome to Follow-Up Friday!

For those new to PuzzleNation Blog, Follow-Up Friday is a chance for us to revisit the subjects of previous posts and update the PuzzleNation audience on how these projects are doing and what these people have been up to in the meantime.

And today, in the spirit of yesterday’s post about The Riddler, I’d like to post a brain teaser for you to solve!

Can you explain the numbering system in this parking lot?

Also, do you have any favorite riddles or brain teasers? Let us know and we might feature them in a future post!
