The bike was impressive, handlebars way up in the air and lots of nice looking colors and chrome. The rider looked like a 'bad dude' and was clearly trying to convey a 'tough guy' image.
You just described half the guys that I ride with... well, you described what they look like on the weekends. Yup! You described a Public Defender, a Prosecutor, a Bailiff, a Stock Broker, a Dentist, and two CPA's... You see, as the Bike culture has become accepted by the general public, and have become "main stream cool", you really can't judge a book by its cover. Look at the Discovery Channel shows; American Chopper, Biker Build Off, etc. Miami Ink, L.A. Ink... Bikes, Choppers, Tattoos; These things have moved from the "wrong side of the tracks" to Main St. Doctors, Lawyers, CPAs, Moms... All now have found a love of things previously taboo. Don't judge a book by its cover.
On the Open Carry thing... I just think it's dumb unless you are in woods or in a rural area. If I ever need to use my pistol to defend my self, I would prefer my attacker to not know that I was packing. Sure, carrying in the open may deter an attacker, having him move on to easier pray, but if he could see the gun on my hip, and was determined... He may just shoot (or stab, or whatever) first. After all its easier to take a wallet off of a dead guy. Plus, a gun would fetch a few hundred bucks minimum, more than the cash that most people carry around every day in their wallet.
P.S. Its not usually the guy on a bike with a gun that you need worry about. Its the one with the ball-peen hammer that means business.
