You all (most?) have cell phones, correct? Every time you have to move to a new range call the Ontario CFO and request a short-term ATT.
"Hi, I'm calling for a short-term ATT please."
"Yes sir, when do you need it?"
"Right now."
"Oh, OK. What is the address?"
"3456 Line Road, My Club, range 3.'
"And where will you be taking the firearm?"
"To 3456 Line Road, My Club, range 1."
"And how long do you need to make the trip sir?"
"Oh, about 45 seconds."
"Sir, are you being serious, or are you trying to waste my time?"
"Oh, I'm completely serious, perhaps you should talk to your boss..."
If every shooter did that at every match, I bet the whole "lock it and bag it " BS would be forgotten in a week.
