Beautiful Oahu Hawaii
*What part of the country do you live in?
Hell if I know. However, I will say this, the largest martial arts cult has to be the Universal Kempo organization. You see their little red stickers affixed to motor vehicles everywhere. From what I've seen on cable access of the system, it's laughable and tragic.
*What's the distribution of MA schools in your area, with a rough percentage of the arts represented?
Small circle ju-jitsu (interesting but impracticable), kajukenbo (absolute garbage), Cajun karate (some weird karate cult that fights for Jesus). As for MMA/NHB fight teams, Egan Inoue runs 'Grappling Unlimited' out of Aiea. http://www.grapplingunlimited.com/Default.asp He's the guy that got K.O.'d recently half a minute into the 1st round of a SuperBrawl match. Many people in attendance I heard were pretty bummed about that. Egan used to be a phenomenal racquetball player before he took up NHB. He even designed his own racquet, the E-Force, which never failed to break apart after a couple of months of play. <img src=icon_smile_dissapprove.gif border=0 align=middle>
*Are there any unique/uncommon martial arts offered in your area besides the normal TKD/Karate/etc, including MMA/NHB fight teams?
If I would have to guess, it's probably very low, but that's pretty much the norm anywhere you go in the world. Most people can't fight, even if they insist they can.
*If you had to guess (unless you know for some reason) what percentage of people in the general community in your area are active participants in the martial arts?
