I NEVER go near the sand with any of my equipment. Sand and external/internal areas of your lenses never has a happy ending. As to snow, as long as your equipment is WEATHER SEALED, their should not be a problem. For rain I always carry a couple of plastic grocery bags in my pocket. If it starts to rain I put my camera and lens into the bag until it stops raining, then I remove it from the plastic grocery bag.
This policy must certainly limit your ability to take pictures in many beautiful places. Certainly would limit travel photography, etc.
