Six people are riding camels and being led in a straight line across a gently rising sandy slope with mountains in the background, by a man walking and holding the tether of the lead camel.
Many people are searching for an oasis in the desert.
They may not be searching for an oasis.
Riding camels in the desert does not imply that one is looking for an oasis.
Only because people are riding camels and walking doesn't necessarily mean they are searhing for an oasis in the desert.
