It doesn't matter that the Tunnel Walk has been around for less than two decades. That's long enough for it to become established as our signature entrance. Touching the Horseshoe by itself isn't much of much. Like everyone's saying - lots of teams touch something on the way out to the field.
I agree, I wasn't trying to negate anything about the tunnel entrance, I suppose more so just being obvious. I do LOVE the tunnel walk though. The key to it all...that low toned pitch from the beginning of the APP Sirius. Gives me goose bumps every time. Especially when I was on the field during my band years and just feeling/hearing the quick gradual roar of the crowd.
