Most vacation spots sport all kinds of souvenirs at shops aimed at tourists. Many of these items were manufactured in other countries and have nothing to do with the location you came to visit. Take home a memory and support local creativity everywhere you go. Visit a club or an area with street performers and buy a CD from a musician.
Choose someone whose music you enjoy and strike up a conversation. Get the CD signed, and you’ve succeeded at supporting someone’s music and acquiring a personalized souvenir and a story to go with it.
