Uh...some of you need to get a purse it sounds like....wow. Hair brushes? Ponytail holders? Make no mistake, I rocked the hippie hair (when I had it), but pony tail holders either go on your wrist, your hair, or your stick shift (hey now!).
And brushes are what girls carry in their purses.
I usually rock Cargo shorts/pants:
Keys are on a a 12 year old carabiner that used to be black, but is now silver.
Front Left: Change (I accumulate unholy amounts of it)
Front Right

hone, folding money
Left Leg: Wallet- I was a courier for a while- sitting on a wallet while driving all day gave me horrible leg pains. Finally figured that out. Plus, everyone has their wallet in back- I like to keep pick pockets on their toes. Plus, I can 'check' to make sure it is there by just doing a little leg jiggle. I don't have to reach back and feel to make sure it is there (which also tips off people where your wallet is).
Right Leg:Smokes, Lighter
Back Left, Back Right:Nada (gotta give the ladies something to look at).
