Thanks to Dave for the very helpful horizon tip -- worked like a charm!
By now, you MUST be tired of all the night shots! That's okay, I have other interesting things to post. Tomorrow, I'm taking the day off and heading downtown. The weatherman says it MAY get to a high of 5F! That's okay, because I'll be indoors at the Field Museum looking at the Jackie O collection. I'll also head over to the Art Institute to see what's on display downstairs in the photography gallery. With any luck, I'll come back with a few nice photos for everyone to see.
