So I am flying out to ORD tonight for my first MR of the year. Actually, I don't believe in pure MRs as life is too short to fly without purpose beyond earning status and miles, so I gave myself 10 hrs in Chicago before heading back to California. And now I am looking for suggestions what to do in those 10 hrs. I arrive around 6am, and I plan to take the Blue Line (?) to downtown. First order of business will be breakfast -- at ORD? In downtown? The weather forecast for tomorrow: "Mostly sunny. Blustery. Highs in the lower 30s. West winds 15 to 25 mph with gusts up to 35 mph at times." I don't like the sound of "blustery"... it supposed to be a "balmy" 65 here today. So maybe some walking along the water front? Some time in a museum to warm up? I have been to the Field Museum on a previous "MR", so maybe the aquarium? Any lunch recommendations beyond "museum cafeteria"? Not looking for something fancy as I'll be tired and un-showered, so some place to sit down, enjoy a light meal, coffee, WiFi and a view would be great... Then, if the weather is good enough that there is actually some visibility, maybe a trip up to the top of the Sears tower (whatever its name is now)... last time I did that was in 1989, I think. Any suggestions or ideas?
