Sounds like early asshole defensive statements. (not you) but I heard this all from Rage fans 2 years ago.
But yeah, saying excuse me and what not, of course gets you far.
Just get to where you wanna be early and you won't have that problem.
Also realizing there is a limit to where you can go eventually is a handy tip as well.
Nothing chaps my ass more than being in the tents, which are crowded enough as it is, with some douche who gets to where I'm at starts pushing when there really isn't any where to go. Yeah, I get it, you want to get to the front. My response would be if you wanted to get to the front, you should have gotten there earlier. I did, which is why I'm standing where I'm standing. And why the people at the front are where they are at.
And please, if you do try to muscle your way through, don't be surprised if you get a couple of well placed elbows shoving you back.
I disagree with number 21, I've had some of my best times in the beer gardens hanging out getting drunk. If you have no one to see for an hour or two it's the best place to be at. Good job on the list though.
