Even before we had to pay for baggage and take off our shoes to get through security, a trip on an airplane was an experience. The flying tube of humanity -- or zoomanity, you might say -- has always been a microcosm of the world at large. Questionable behavior and good intentions sitting cheek to cheek. Yes, those cheeks.

It's time for a confession: Every time a neighbor puts up a For Sale sign with an information tube, we're one of the first to pull a flier.

It's not that we're looking for homes for sale, we just want to see how much the neighbors are asking. Given expertise gained from too much time spent on Zillow.com, the real estate site, we feel we have a good idea what the price should be.
