We met some interesting people sitting in thr cheap restaurants on the beach at the corner of the town. The places were basically big tents with tables and chairs. They served cold beer and cheap set meals. By early evening the clientele shifted from tourists eating to the 'getting pissed on the beach' crew of locals and visitors. We saw this all over South America, especially at the weekend - gangs of people boozing, shouting and listening to salsa music. I think the cheapest beach beer I found was $1 for a large beer in Equator.
Anyway, Mancora is in Peru. It seems unusual for Peru as it feels tropical - it is squeezed into the north west coast, an hour from the Ecuadorian border. It is a fun city for Peru, and more fun for me than the dumb oasis town of Huacachina.
