Bus from Manali to Leh. Takes fucking 20 hours on the bumpiest road and while I didn't get altitude sickness, every time you go to sleep you wake up three minutes later feeling out of breath. Surrounded by stinking Indians. Bus driver doesn't sleep, just pulls over ever 5 hours to more Chai. Bus driver takes "short cuts" which really just mean off-roading the bus in the fucking Himalayas. Very few guard rails. Looked over the side few times, once I saw a bulldozer that had clearly fallen 1,000 feet down, just sitting there, wrecked. If you want to shit you have to do it when the bus stops, and they don't got toilets nowhere, so even though it is in the middle of nowhere, there are piles of frozen human shit all around. Nice views, terrible sleep.
