On the way home from Tracy MN last night at sunset, level at 9000'. Bases were at about 700' with 2 miles visibility but tops were only about 5000 and clear above.
I kept thinking about Steve51B describing altitudes in this range as "Indian Country", since that's where oil burners come down and find Apaches, Cherokees, Seminoles, Aztecs, Comanches, and lots of other Piper products named after native Americans. Last night, though, I think was the only one around under FL290 until I got close to the Minneapolis class B airspace.
I love the way the plexi distorted the sunset - it looks somewhat ethereal to me in this view. The fuzzy haze layer just on top of the clouds probably has something to with this this, too. Whatever the cause, I like the effect.
