I had 10,000 in cash back when I was 23 or so because I lived in the Caribbean and was a stupid fuck. I cashed all my paychecks at once when I was moving back to the states and instead of getting a bank check I asked for cash. The people in the bank all looked at each other. It took like 20 minutes but they handed me two fat envelopes filled with cash. It was pretty fucking scary, actually, because as I hitchiked rides back to my house I just had a backpack with 10 large in it and I could have sworn all the West Indian locals were going to machete my white ass, fuck my corpse, and take the cash.
Ended up blowing the wad of cash with my ex wife at the time in just a few months. If I knew then what I do now, I would have done something intelligent with the money and would still have some of it now!
