If I have to wear a beret, I'll just stop listening to music instead. 
LOL LOL dam near spit my drink out....
wow, I almost owe you a drink

Thanks guys and gals for the PMs, I thought I might know everything except a model, but I got a little more good advice as well.
Even after 100+ shows there are still a few new ideas.
be sure to get the "duckbill" beret. more room.
I met up with a fellow taper for a show in Colorado awhile back (im an Ohio guy) and ol Billy had a beret, I couldn't stop laughing, I had to go to another entrance, or I'm sure I would have given him away. He took in a set of mics, a pre, 2 dat decks, a wireless decoder, cables etc. After the show I asked if he wanted to compare tapes and my rig was worn so ninjaesque he didn't realize I was taping stnading next to him for 2.5 hours

I prefer the ghillie suit for clandestine activities.

I'm pretty sure the ghillie suit might raise an eyebrow even from the dullest of event security

Heck bring back the parachute pants with your new lid to complete the ensemble with a retro mid 80's look. 
fat 40 year old guy in the parachute pants, i'm too nice to make anyone look at that
