Eddie, I almost attended a business conference in Banff a couple of years ago. I didn't go but heard nothing about any problems with the 500+ attendees. Surely not all of them had lily white backgrounds.
I guess it is possible for convention attendees to be excluded from scrutiny. It would cause the cancellation of too many $$$ making conventions/business meetings.
I guess it would be best for me to not even attempt to get in. When Lusk, Otto and I went to Atlanta, I found that I was on the No Fly Terrorist List. I had to step aside for about 30 minutes while they straightened it out. I doubt that I would want to hire a Lawyer to go fishing.
Wood, we have the same thoughts about Guvmint here. In my case, it gives me something to think about while the A/C is being repaired.
