I left college and went off to live in Nepal for awhile when I was 19. (It sounds far more rebellious and crazy than it really was.) One of my favorite memories of my time there is of the Hindu festival of Holi. It celebrates the end of winter and the start of spring and for days and days people throw brightly colored powder on each other.
I saw these and other wonderful photos of this year's festival here and it brought back memories so strong I could almost smell them.
