Does anyone cook their evening meal at a different location than where they sleep? I mean: Stop to cook dinner, then ride a bit more to find a great sleeping spot and set up camp knowing you haven't broadcast your location to any animals with a nose within miles by cooking where you sleep?

Many backpackers that do this rarely have to bother with hanging their smell-ables so long as the bag is reasonably airtight. Exceptions include when you are near human habitations that critters frequent for a free meal, like campgrounds or city parks.
