Human Factors; Airport
Denver; is a high altitude airport with very long runways and a potential of wind conditions associated with the mountains and the front range.  I noticed that all the runways in Denver only have wind socks at the end of the runways; when they should have at least 1 or 2 more down the runway as the winds in high altitude airports change during frontal systems.  On Runway 25 the wind sock is between the runway and the taxiway and is in a valley almost below the taxiway and the runway.  We need more immediate visual clues on takeoff roll which is usually a lot longer at high altitude airports.
Pilot believes that DEN airport has insufficient wind socks when the altitude and length of the runways is considered.
