Let the fans have fun no need to complain
Normally I'd agree, but the horn thing is different.
1. It's a few fans sitting very close to the TSN booth window causing all the problems.
2. You can hear the 1 to 3 individual horns distinctly, It's not general drone noise like at IGF or Mosaic. There is a big difference in annoyance factor on tv.
3. It works like a compressed air horn (but it's hand-operated) which is outlawed in every CFL stadium in Canada.
I have a few easy solutions that might even allow the horn fans to be happy:
A. Designate the sections all around the booth as horn-free. If you have to, designate the whole side horn-free. Horny fans can trade their STs for the other side. This will instantly solve the on-TV problem. The horny fans can still horndog away from the booth.
B. (More drastic) Outlaw that type of horn and give them all an option to trade-up to a Bomber-style blow trumpet.
I'm not sure why everyone is finally, now, in a tiff about the MTL horns: they've been doing this for many years! I've complained about it in the past. If it's gotten worse it's because someone has gotten STs right near the booth. You gotta protect that area around the booth.
