Greetings, This is a silly question, but as I pack my bags in order to depart for Nicaragua tomorrow morning, I'm wondering if I'll need my rain parka. I used it a bit when hiking in Panama and Costa Rica in the higher elevations. But overall, I never touched it. Is it really necessary? Any other items of clothing--or any items--recommended to bring or not worth packing? I'll be in Nicaragua till mid May. Thanks. Judi
