Thanks, hhEb09'1.

The cities of the now defunct GDR (or of other Warsaw Pact countries) may have had nothing much in common with the sprawling, touristy, upscale centres of tourism on Hawai'i's Big Island.

After dark, however, I saw one striking similarity when I visited Hawai'i this past February. While the phenomenon was born out of need in the GDR, it is there by intention in Kona.

What do you think the phenomenon is, and why is it there to see?
