I'd appreciate any advice on taking care of my gear down in Nicaragua and Costa Rica. Going for 17 days, splitting the time between the two countries. It's rainy season in many areas, high humidity. Taking my one Nikon D90 body, and two lenses, a Nikon 17-55mm f/2.8 and a 70-200mm f/2.8. Also a back up point and shoot, the Canon G9. Will have a Storm Jacket cover, (and Ziploc bags!) but really wondering about storage during at the end of the day when not in use, lens changing tips in these conditions, basically anything you can offer! Leaving this Thursday, July 8th. Thanks!
