In Bulgaria, there is a tradition called July Morning dating from the hippy period in 1980s and maybe as far back as the 1970s. Young (and not so young) people from all over the country travel (often hitchhike) to the Black Sea coast to meet the first sun rays on the 1st of July. Naturally Uriah Heep's July Morning is the main refrain. Although the tradition is linked to the hippy movement in America, it is still popular in Bulgaria. Strangely, it seems that there is no such tradition in other European countries.
