I have some odd dreams, on occasion.

See, at the end of one recent Roo Cam session,  Tim_Kangaroo exhorted us all, "Good night, bronies! Dream of ponies!" And, the following evening, I had an odd dream where the numbered shields on highway signs were replaced by pony heads!

Anyhoo, I mentioned this on Roo Cam a day or two later, and  The kinky turtle ran with the idea, as you see here. I figured it was too cute not to share, so here ya go!

(Incidentally, KT ran this by one of his other IRC chats, and the consensus was that earth ponies ran north-south and pegasi ran east-west. Presumably, unicorns were for bypasses and beltways.)

Original concept © moi. Artwork by  The kinky turtle. Pinkie Pie © Hasbro. Interstate shield © USDOT, I suppose. Incidentally, KT drew the shield in Photoshop from official specs, down to the fonts. Now THAT is what I call attention to detail!
