Is short course racing slowing?

[Modding_out]

I want to get back into rc and try to do a bit of racing, specifically short course. Is it still going crazy like it did 1 1/2 years ago? I would like to ride the tail end of the wave if it's going the way of the monster truck races.
I just want to race at the local track. What trucks would I be going up against if I converted a HPI 4x4 nitro MT2 too roar legal dimensions?
