For the rainy season, get everybody properly outfitted to avoid getting soak. Pack raincoats and folding umbrellas in bags and backpacks so you will be ready for anything. Slip in clean, folded zip-top bag too. You may not be able to prevent the entire bag from getting drenched, but valuables like your new unlocked cell phones have somewhere to go to be kept safe and dry. You don’t want to waste a valuable thing, right? So, secure your stuff before heading out.
