In answer to your question: I used to call and ask people questions at AAPT. I used to believe the PR's (40,000, 60,000 stores) Straight answers seem very hard to come by. I used to talk to people at AAPT, and post the answers here. I believe I misled people doing so.
I would like to write them and get answers in writing.
But, They don't even have an email address listed on the website.. that would be a great communication technique. It would be fantastic to write a question and get an answer which could be posted.
