We're Counting On Boulders

On a recent visit to the new Castro Valley Library, Your Boulevardier noticed that one of the boulders near the footbridge has an identifying number.



Truth is, when the boulders were delivered many weeks ago, it was noticed (but not posted, alas) that all of the stones were marked with numbers. Your Boulevardier was tempted to make a remark about tagging, but let it go. Now, it is guessed, those numbers were used by the landscape architect to direct heavy equipment the placement of the boulders.
