Welcome, Graham! I'd love to see the collection of someone with your particular experience. I hope you'll post some pictures!
And that's a great avatar -- Inspector Clouseau as RCMP...? Is there more to that particular work? If you have more graffiti like that around, I'd love to see photos of that, too! Is that in Ontario? (I would've guessed Quebec, but I'm Minnesotan, & I have a lot to learn about our neighbors to the north.)
