Since 1959 the Indian Border Security Force and the Pakistan Rangers have carried out a flag lowering ceremony to mark the end of each day when the border gate between the two countries slams shut.  Guards both from both countries perform a goose stepping routine to the cheers of stands full of patriotic locals and tourists. I went through more security checks than at an airport (4!), the extra checks are probably since a bomb attack a few years ago sadly killed 60 spectators and injured many more on the Pakistan side of the border.
