Nice info OldSF3......good to learn something new.

My 0.02 regarding the backpack, earbuds, etc.
1) I can see where one would need a rollerboard, a flight case, an extra bag (backpack) because you might be gone for a while, and possibly a snack/lunch bag 'cause you need to save money...Total 4......Anything above that......seriously?.
2) If you have a hat anywhere around you, wear the damn thing in PUBLIC. Obviously you MUST wear it.
3) Why are your pants a different color shade from your jacket?.
4) If the stripes on your spaulets are close to the color of your pants, WASH THEM.
5) Flight cases are CASES to carry your necessary equipment for FLIGHT. Although it is your case, and might be your opinions, if said case is being held by nothing but bumper stickers, it's time for a new one. A few stickers are ok, but if one can't tell what material that case is made of, YOU HAVE TOO MANY STICKERS.
6) Lastly but not least, we get paid (some very well, others not so) to be PROFESSIONALS. Part of being a PROFESSIONAL is to look like a PROFESSIONAL. I have yet to see a Doctor, Attorney, Engineer, or other PROFESSIONALS looking like some PROFESSIONAL PILOTS while in public.

Ok, feel better now, thanks.
