Riding at sunset

It was my daughter's fortnightly riding lesson tonight, where I sit around in the cold for two hours, working on my chilblains.
At this time of the year, most of the riding is done in the dark (with floodlights) and we had a lovely sunset tonight, just as they had gone into the arena.

Still trying to figure out the whole raw file thing - whether to use Camera Raw and PS or do it all in Aperture? Need to get a workflow thing happening!
