The lowering flag ceremony at the border at Wagah between India and Pakistan has been going on since 1948. It's a wicked theateral show, where the border guards try to out-do each in down steering, shouting, and silly walks. It's a big attraction on both sides and there are stadium size sitting area on both sides (though the Indians is way bigger). When the border closes at 4 pm you are allowed to enter the sitting area. Both sides start to blast patriotic music on max volume out of big loudspeakers, while cheerleaders (males) are getting the crowd pumped. The actual flag lowering ceremony starts a sunset at around 5:30 pm and is free of charge. Times might change whether it's summer or winter, check before going, and remember your passport.
