What would make me drop this sport after 20+ years = untouchables.
Live ammo is a must, haven't seen that mentioned.
Cowboy era is a must so western clothing is required.
CAS has to remain an amateur sport without sponsored shooters(advertising as such) or prizes based on placement.
VARIETY is essential, I am not a golfer but I can't imagine going to the same course time after time and doing the same thing over and over again. Ruts and stagnation will doom anything.
I have shot matches with stage titles and procedures and no story or set-up and I have shot matches with aspiring novelists with a long story/ set-up. I much prefer a nice short story and set-up. Without it we are just shooting and I can do that without travel and other expenses.
