Everglades Building Thunderstorm

After shooting a sunset one morning I noticed some building clouds on the drive home.  I decided to pull over and watch them for a little while to see if they continued to build.  After about 15 minutes or so they continued to climb skyward and then started producing some rain.  They never did produce lightning or thunder but still made for some dramatic skies over the sawgrass prairies.  I also decided to try an HDR shot of the storm in order try and capture the dynamic range of the clouds.
