The last time I did it, I was 12. Parents wouldn't let me do it anymore.  BUT. Then I did it again when I was 24, just to see if I could get away with it. I was with a few kids so I wasn't alone, I was covered up completely, used a higher voice, and being 4'11 you couldn't tell how old I was. I was pretty skinny too as that was around the time of my worst health, so I only did a few blocks before I couldn't do more.  But I did it. Sorry Cars, please don't be dissapointed in me, you are our lord and savior.
