I just purchased a underwater camera kit including strobes, focus light, digital camera and housing. Since I want to be prepared, I'm putting together a "first aid kit" in case of flooding. However, is it worthwhile to carrying a bottle (1 liter) of distilled water or is distilled water readily available in most areas? I would think distilled water would be hard to find in most regions. Please let me know what other people do or carry in their "first aid kit". Thanks
