OMG! You have a GT Mach One?!
That was my first real BMX bike! I got it for my bday in the 6th grade! It was white just like yours. I even wrote a short story about it and won a district wide author's award!
and i bought i from a former coworker for the hefty price of $20 a couple years ago....i jumped on the chance because i never got to have a good bmx bike when i was a kid, i had some hand-me-down frankenstien kmart bike
the frame isn't in the best shape, one of the rear dropouts is kind of deformed and i replaced a bunch of stuff (including the horrible "dominator" plastic seat lol) but its a blast.
congrats on the award!
in it to ride, not to accessorize.
