Get out and experiment...

...with your camera, that is.  As I was sitting around during this monsoon we're getting on the east coast, I was thinking how I haven't been shooting at leisure as much as I used to.  So I picked up my weather-sealed Nikon and went outside and played in the buckets of rain falling from the sky.  Although I didn't get anything exceptionally profound, I did remember that it's better to pick up and shoot crap, than to not shoot at all.
