The BIGGEST???

[mookien]

If you check Wikipedia under Glengarry Highland Games in Maxville, Ontario you will see the claim that they are the largest games outside of Scotland. Who knows. Depends on what you count. As home to the North American Pipe Band Championship, they draw in the order of 50,000 folks each year. They certainly have a lot of bands competing.

I did check Wikipedia under "Glengarry Highland Games". The article states ...

"The games span three days and attract as many as 50,000 people, they are the largest Highland Games of its kind outside of Scotland."

I can't imagine what "of its kind" means. And you are correct - it depends on what metric one uses - number of participants, number of attendees, number of bands, hidage, tonnage, etc.
