Louisville Kentucky is fun. Sure, there are idiot drivers sometimes, but they are everywhere.
If it wasn't fun to ride here, I wouldn't do it.
There are some cycling-friendly dining and drinking opportunities (we took advantage of several of them on
this ride).
Roads near the city center are pretty good for cycling. Lots of one-way streets, many lanes, a few bike lanes, make for easy getting around, and painless to take the lane.
As you get further out, it's less easy, but sometimes you find a new route. If you get out to the rural roads, there are beautiful low-traffic areas with rolling hills.
I like it here.
