TALLIN, ESTONIA-- Top of the tower... where people can "edgewalk." People first sign a waiver of liability agreement, pay a $17 fee, and are strapped to safety harnesses. Then you are free to test the strength of the safety harness, and enjoy spectacular--and somewhat windy-- views without fences and other obstacles.
Other than fear and the blood rushing to your head.
A year ago, the owners of the tower allowed parachutists to jump off.
