I've traveled quite a lot in my life, but I'm not much of a souvenir buyer. I bought a woven scarf in Costa Rica, even though I'm pretty sure I could have bought it in the States. I'll always remember the shop where I bought it and how hot the weather was that day and how we had difficulty understanding the shopkeeper's English, since my Spanish is almost non-existent. So the scarf makes me remember. Voila! It's a souvenir.
