Ryan, nobody has said anything untrue about you here, have they? Was this bike not recently acquired from CL? I believe it was. Yet you say your dad picked it up many years ago....interesting. As for the threatening emails you received, what were the threats? I recall you emailed a friend of mine and threatened to "pay him a visit" when he called you on another tired lie you'd been caught in.
It's OK that you're in the flip game, brother. Lots of folks are. The only collectors/flippers who last, however, are the honest ones. Maybe try the BMX forums next?
