Perhaps so. I personally can't see Vegas and that date on the billboard. Maybe you have a different version of the photo.
Can't imagine why he might not visit a place called Dell's Mills? And perhaps go to the UFC there http://www.mmamania.com/2011/5/10/2...debut-in-milwaukee-wisconsin-for-the-upcoming
Still, the point is, IMO he may be a fan of Hardy who fought there http://en.wikipedia.org/wiki/UFC_Live:_Hardy_vs._Lytle thus the reason for the hairdo.
I hadn't looked at UFC to see the red mohawk connection, but that doesn't surprise me at all.

Cabo Cantina is one of the few places that would be showing the fights on their TVs
and a link to Google maps "Inside view" of the Cabo Cantina at Pacific Beach (You can tour around a bit inside just like you look around on street view in google maps) Doesn't look quite like the picture of DM

I saw a few pictures from the Santa Monica location, and it could be that one, but nothing to say it was there for sure either... just a fun exercise to try and find it.
