5. Wear too much leather
Leather garments are beautiful, perpetually fashionable and, in most cases, make an effective statement -- but they are not good in hot weather. It is painful to the point of heartbreaking to see guys and dolls alike walking around during PrideFest clad in cowhide from head to toe, sweating like altar boys at Catholic bible study, and there isn't a CostCo-sized shaker of baby powder big enough to combat the pouring sweats, dehydration and swamp-crotch that results from bullheaded Pride attire. To save yourself from being totally miserable, why not a compromise? By all means, wear some leather -- but don't go to PrideFest all full-on biker. Maybe just a vest, or a hat, or a corset or skinny pants -- but just one of these things, and if you must express yourself with the tightest of tight Bowie-bottoms, at the very least make sure you wear some breathable underpants so that your lips and bits aren't glued to the inside of your trousers.
4. Get too wasted on booze
"We're here! We're Queer! Let's drink some beer!" is one of the massive appeals of PrideFest every year, because who doesn't want (or need) a reason to wear body glitter and see exactly how many plastic cups of Bud Light it takes to make you want to almost-naked crowd-surf off the side of a rainbow-parade float. But that being said, it will certainly be hot and humid this weekend, and you will want to suck back ice-cold brews like they were cups of awesome juice. Keep in mind, though, that you are in the midst of a ton of people with memory-recall -- and phone cameras that take better and better pictures with every phone upgrade.
Doing fucked-up shit when you are sauced at PrideFest is kinda like the same terrible fuck-ups you make the rest of the year, only during Pride you are really sweaty and screwing up in front of thousands of people instead of fifty people at a bar, some of whom will put your balls-out, bare-breasted shenanigans on Tumbler faster than it takes for you to splash water on your face. And your mother is probably on Facebook.
3. Harass the bisexuals
Bisexuality exists, it is real and an actual sexual identity that some people choose to identify as. Bisexual people are not "free for the taking," they're no more or less promiscuous than anyone else, and they really don't like being labeled and hounded about their sexuality or told they are confused or need to pick a side. Remember this when you are out and about at PrideFest, mingling with different kinds of folks, because yes, Pride is a lot about sexuality and sexual politics, but it's best to stick to the positive kind of politikin' for a gathering focused on celebrating diversity. And keep in mind that the people opposed to homosexual marriage and gay rights don't discriminate -- they lump bi people in with the gay people, and you are on the same side.
