Bring Back Motel Roadside Message Boards?

I like those old-school motel roadside message boards that seem to be more prevalent in America. It's a concept that has never really caught on in New Zealand (some may say that that this is a good thing), however I'd like to see the signs make an appearance here to add to the roadside architecture.

Moteliers could use the boards to share with the world their latest offer or quirky thought of the day. There is a risk, that the motel owner may not possess appropriate humour and a few may struggle with the English language.

Unfortunately moteliers may not have time to upkeep the signs and those mischievous neighborhood kids could easily offend by amending those tacky plastic letters;-)
