I have found that it's best not to go on trips contemplating great photography with someone who is not interested or involved. It is seldom satisfactory for either party. You need to be able to concentrate on finding good viewpoints and compositions without worrying about whether or not your partner/friend is dying of boredom. Walks, or other outings with non-photographers can be a good opportunity to check out the photographic potential of a location. Most times you can plan a return visit purely for photography.
