Shotgun Geniez

You get to see quite a few interesting signs, sculptures, buildings, advertisements, etc, when you drive across the country. This is one of our favorites.

A few clues letting you know this must be one classy joint.
1 - It's closed on Sundays, at least after 4 am.
2 - Only high class acts would want to perform at "Shotgun Geniez Performing Arts Center"
3 - The sign is painted on a semi-trailer.
4 - The sign is located in the middle of nowhere Nebraska.
