My second year living in Barcelona, my host family asked me "Hey, want to go looking for mushrooms in the mountains?" I thought they were joking, but it turns out that it is a super popular activity in the autumn here in Catalonia. If there's one thing I've learned in all of my travel experiences, it's that it is almost always better to say "yes" to an opportunity. And so off we went to Montseny, a mountain range near Barcelona.
