Alot of the people that respect single cams are the people who have been in the game for a while...Back in the day it was have a stock single cam or have a modded single cam. Believe it or not, but there was a time there was no swaps. The single cam platform is where it all started, kids these days know that.
So to answer your question, Im sure there are alot of poeple up there that rock the D, but it could be possible that the "scene" up there started getting big when swapping motors became popular...maybe they never gave the single cams a chance, who knows.
