And before you say it, I know what you're thinking: "You stupid contrarian hipster, of course you don't like the JMT. And you haven't even hiked it! Your opinion is garbage." True, sure, but unless you want to reread the 3rd thread about dogs, you're gonna read the rest of my stupid post because it's March.
Three Reasons the JMT Sucks
1) Logistics: The car shuttle, the permits, mailing yourself food, and most importantly the fact that it's 200 something miles, which even if you're taking a 14 day vacation barely fits into anyone's life. It's always strange to me that in order to go hiking on this trail, you probably need todownload this bot to apply for a permit the instant they become available. In the future, the JMT will be nothing but hackers & software engineers, and will turn into a great networking event for the software industry. Those folks don't bathe anyways, no one will notice they've been on trail for 8 days.
2) The Jolly Manure Trench doesn't actually go to the coolest stuff: Here's a list of things the JMT doesn't see: the biggest glacier in the Sierra, the biggest trees on earth, the deepest canyon in the US, the tallest waterfall in the US. It misses the entire eastern side of the crest, too. Here's two random pictures I stole from other members that aren't on the JMT, because why not:


The Justa Million Tourists is really just a highway, connecting places in the Sierra. It technically doesn't even go to any of these places in Yosemite: Half Dome, Clouds Rest, and Vernal Fall. No one loves I-40 for crossing the US, so stop putting stupid JMT stickers on your Prius.
3) The route is mostly poop: Between mules, campers who suck at cat holes, and animal scat, the amount of poop you will encounter on the plodding class 1 slogfest is staggering. "Ah", you say, "you haven't hiked the JMT, so how do you know?!" Because the state of California was so concerned about the amount of poop on the trail, they had UC Davis study it. Given the slow rate at which alpine plants grow, scientists estimate 90% of the soil organic matter along the JMT is former poop. I may have made up that last fact, but you get the idea. Unless you're down for alpine scat night, skip the JMT.
