Thank you, all these advices are really helpful. Definitely I'm traveling on a budget so I want to spend the less i can.
And dmac, yeah. I'll upload some pictures, i have tons. Just let me look for them. Would you guys recommend starting a new thread for uploading pictures? I live in concepción, la unión. It's in the center of the country, it's mountainous, and colder than most of the country, you can look on Google maps
