There are far LESS corps nationwide, and just a handful of "championship" level corps that everyone knows - Cavaliers, Cadets, Scouts, Phantom, BD, SCV, Bluecoats, Boston, Xmen at the junior level, so there's less of a "community" feel to most corps since there are so few competitive ones left these days.
This loss of community is what I feel the most. Well stated. I dont intend to be one of the ones bashing todays activity, and I hope I dont ever come across as that, but I do think that as corps have folded and the activity has changed it is only natural for some people to miss the old days or the old corps or the way things used to be.
