The city of Chicago is famous for having the "Welcome to Chicago" and "Welcome to O'Hare International Airport" sign over their freeway system... (think back to the intro for 80's show Perfect Strangers - see attached video - about 20 secs in)...

We should add signs over the freeway system (in each direction) as people are about to drive into the city on I29 and I94. The pictures should be done professionally and be things that folks identify with Fargo... like the Fargo Theater Marquee...

This is an excellent opportunity to brand the city and have people from other states start calling us by that name... I'm thinking "Silicon Prairie"... I think we'd be the first city (even though several refer to themselves as this) to explicitly call it out.

We should also have smaller signs around the city like "Welcome to Downtown - We're Glad Your Here!", "Now Leaving Downtown Fargo - We look forward to seeing you soon!"

Here's a few ideas:

Welcome to Fargo - the Silicon Prairie
Welcome to Fargo - the Gateway to North Dakota
Welcome to Fargo - home of the NDSU Bison
Welcome to Fargo - our roads are definitely better than MN
