We were driving on a terribly potholed road in Mexico's Yucatan Penninsula when I saw this rad bloom fighting to extricate itself from the limestone dust which covered everything. Had to record it! Photo taken December 20o9 with a Sony A-700 at ISO 200 using f:9.0 and 1/60 sec exposure. I used a Sony 18-200 lens at 200mm focal length.
