Last night a friend regailed us with a description of the underground tunnel connecting the concourses in the Detroit Metro Airport, and I hesitantly admit that I was suspicious enough of the bizarrely psychadelic nature of the display that he described that I jumped on line and confirmed that commuters through Detriot do indeed get treated to “a wonderful light and sound show” as they rush from gate to gate (select item 7 in the virtual tour for a poor rendition of the tunnel). I’m almost hoping for a layover there sometime, now.
