Thanks Hugh. We have the Western Ghats to the east so we get some light before we see the sun. If we have some nice cloud cover then we can get some very cool reflected light. If I see a really nice sunrise, from my house on a hill, by the time I get my gear and take the jeep to a good vantage point the moment is gone. The only way I can do it is to leave when it is still dark and hope for good sunrise and skies. Works sometimes and not others.
