I was astounded at the number of billboards in Los Angeles. As soon as you leave the airport and hit the road, bam! One almost on top of the next. This view of the Sunset Strip from my room in what was then called the Wyndham Bel Age (and is now “reimagined” as The London), is mild compared to other neighborhoods. But even so, you can see two billboards for Bose QuietComfort 2 headphones, the installation of which occasioned my visit.
