@ Jason -- Well, it seems you're not supposed to photograph anything on government property, without prior approval. Ooops!
I was visiting a friend's father at the local Veteran's Administration Hospital when some new construction caught my eye. From the parking lot, I pulled out my camera and started shooting . . . until I heard yells to "Stop! Now!" and was rushed by several burly security guards. (Dudes! Chill!)
Of course I wouldn't hand over my camera or memory card, so I was 'escorted' into the in-hospital police sub-division for a few questions, then further escorted to the office of a hospital administrator for more 'chat'.
After handing out business cards and showing off my website and blog (to prove I was an artist -- not a terrorist), I was allowed back to the parking lot -- with appropriate escort -- and allowed to photograph the crane, using LCD screen instead of viewfinder, so that my 'escort' could clearly double-check (heavy breathing over my shoulder) what I was zooming in on.
Luckily, all the activity attracted curious, previously bored, bystanders, and I chatted and handed out a big stack of cards that day! :-) Oy, what an intense way to spend a hot, South Texas afternoon!
Moral of the story:
1. Always follow the rules.
2. If you don't follow the rules, always play it cool and work the situation to your advantage!
3. Never take advice from someone who doesn't follow the rules. You might get yourself arrested. ;-)
P.S. Glad you like the video!
