It seems to me that both sides of the issue are taking themselves to seriously. Lighten up...some of this stuff really is funny!
It really isn't that important but you know what. I am an OLDER THAN THE HILLS and I remember when backpacks didn't even exist. How on earth did we survive without every single possession we have with us constantly. I have been to WDW 17 times and have never had the need to bring more stuff with me then could fit in a fanny pack. How did I ever survive?
