WordPress issues a weekly photo challenge and this week’s theme is “Descent”. If it goes up, it must come down. Descent, down a hill, staircase, waterfall…I like to go up in high places when visiting cities, many of which have observation towers. Observations wheels are becoming popular too, since the London Eye was such a hit. Some cities, like Vienna, have had an observation wheel for a century, somewhere I’d love to go someday.
