2 questions...for the price of one!

Two questions for you fellow Chicagoans to ponder on this fine winter day. No heavy thinking required: ************************************ 1. Imagine they will be building an 80 story condominium in Chicago. You will be buying a condo on the 80th floor. You're buying for the skyline view. And you have only one exposure: north, south, east, or west. Strictly on the basis of skyline view (no other cosiderations allowed), what location in Chicago would your building be and what direction would you face? Restrictions: you don't have to be downtown if you think a north, west, or south side site could allow you to see the entire sweep of the skyline. you can't build on parkland or in Lake Michigan. ******************************************* 2. Good news. You're still moving into a condo. You'll still be on the 80th floor. But this time, we'll choose a location for you: somewhere in the heart of downtown. Now we'll throw in some special (and incredible) technology for you: the entire residential section of this circularly-shapred tower revolves. Make that one rotation every 1.5 hours. Assuming all works well with the technology, how do you feel about the rotation concept...something you'd like or dislike...and why?>
