Yeah this is true.
Exactly one year ago i was down there to attend the Transformers convention "BotCon" in Pasadena.
While i was there i visited Frank n Sons, and it was awesome!
I was filming inside with my video camera for about 20 minutes or so when a guy comes up to tell me to put away the camera. I thought hw was playing around and i told him "yeah right!".
He then told me, that he was head of security and the place was private property and there was no filming allowed without permission from the owner.
So he escorted my ass back to my truck and made me put the camera away.
Wow they were strict about that rule and caught me off guard!
Well now i know, at least i got some footage before they caught me, LOL!!
haha, so that must've been you that I saw then.
