The thread is simple. Post your top 5 or top 10 NHL traditions that epitomize the spirit of the sport/league, things that made it great for your childhood, something that captures the spirit/environment, so forth. If this is vague, I'll give examples.
Goal horns, hockey night in Canada, Don Cherry's apparel, winter classic, hockey pads, fighting, waffles, Maple leafs perennial losing, etc.
I think making a top 5 or top 10 list would be better and make it more interesting as opposed to just blurting out what you like because we probably all share the same answer(s).
