Louisville is a terrific city to live in. It is solving traffic woes that hit Nashville's expansions like the kiss at the end of a hot wet fist. It grows slowly, keeping a reasonably fully employed citizenry above the Mendoza Line of feeding and housing. Already blessed with a ludicrous number of elegant middle class neighborhoods, Louisville strikes the visitor who explores extensively as completely well-planned....which it was, thanks to far seeing city fathers who hired Frederick Olmstead to plan the city and then implement it before the turn of the 20th Century. Really fortunate in that aspect, avoiding a laundry list of predictable physical civic problems. The building of the Waterfront Park, The Yum!, the new bridges, the exceptional care put into the Main Street tourist location including the best hotel in America - C 21 - the new Botanical Gardens being worked now - none of this is splashy like the new wave spikes of skyscrapers ripping the skies or looking purposefully attention-grabbing.
Louisville has the benefit of relaxation, reasonably good taste and some level of security which is not only admirable but which is decidedly human. It is a terrific place to live, by any criterion. I have lived in the Left Coasts world's great cities - Vancouver, Portland, Reno and San Francisco - and trust me, living here is every bit as interesting as you want to make it, with many of the same qualities of culture and better weather, lol. If, of course, you happen to not like rain every day and sunless months of the Northwest.
