Low fares, no hidden fees

Outside my window is this Southwest billboard. Last night I thought I'd play around with it in my lens. This shutter length was 1.5 seconds and I just zoomed out from the billboard in that time. Usually the Southwest billboard phrases are pretty witty. Unfortunately this one is not, but they will probably change it soon enough. Ironically though it's about travel, and just yesterday I was telling a friend I was running out of photographic inspiration here in Dallas and needed to travel. She had just been to Niagara and said it was beautiful and cycler friendly.

I wonder what the low fare, no hidden fee is to Niagara?
