I think there is.
Yesterday, I saw a kickboxing/karate MMA school that was next to an Aikido school. Just a few miles up the road was a Taekwondo school, also next to a local gym that offered various martial arts programs. And I know also that, not too far away, were two more martial arts schools.
I checked the other suburbs in my city, and it seems that there are half a dozen schools in every suburb, all offering programs in training, fitness, self defence, and so on.
With our economy the way it is, I think the boom in MA schools will become a bust. IOW, quite a few schools will shut down.
Does anyone else share the same feelings?
