Great sunset shooting advice

Jim Harmer has some really great advice on shooting sunsets (and sunrises) over at Nikon's website. I agree with everything he has to say, especially finding something to put in the foreground. Like him, I've skipped shooting some spectacular skies because I couldn't find anything to put in front of them.

Here are a couple similar sunset compositions taken about 200 miles apart from each other at Devils Tower, Wyoming and Pierre, South Dakota.
