Where is Oakland? Is it in Asturias? Is it in Spain? Is it in Europe?

Yes, you are right. No it isn´t in Europe. Oakland is in California, U.S.A. And this month we have written some letters to our penpals from Esperanza Academy. It´s challenging for us to write in English, but we have made our best and we have enjoyed writing them. We hope you like them, dear friends.
