Well, duh. If you do only one thing on this list, this should most definitely be it. After all, you only need to have watched this historic annual event on the WWE Network to know just how essential it is as a wrestling fan to make the effort to actually attend one of them in person. WrestleMania is pretty much the only WWE event where it doesn't matter what seat you end up in. Front row or so high that you best hope you don't suffer from vertigo, it's being there that matters, and getting to say you were at a certain WrestleMania when history was made puts you in an elite and very lucky group. Even a bad WrestleMania has moments which any fan would be lucky to see with their own two eyes, while the feeling of being in a gigantic stadium with such a huge number of people who all love the same thing is no doubt electric. Speaking of the crowd, there's nothing else like the vocal international audience who gather at WrestleMania each year, and that too is sure to add to he overall experience. Throw in the other goings on which surround WrestleMania like the Hall of Fame, Axxess, and of course the always awesome Monday Night Raw which follows (I guess NXT should now be added to that list), and going is clearly a once in a lifetime experience - I'll forever be jealous of those who got to see Daniel Bryan's big moment in New Orleans - which every wrestling fan should strive to do at least once.
