I have found that in my older years, I'm 76, I actually enjoy CAS MORE if I go less! I know that may seem weird, but going every week is becoming a chore. I look forward to 2 shoots a month, maybe 3 and I'm done with the 3 day shoots. I have 5 different shoots that I can choose from every month within 1-2 hours. Oh yea and then there's the weather also, too cold, too hot, raining NO THANK YOU!
I don't see any sweeps that are hard to do, some make you think a bit but that's okay. It's good to use your brain was you age!
