FYI: Site & Experience Classification: The travel industry often classifies travel sites & experiences as:

    Tier 1: …. usually globally recognized & revered sites:
                     Paris’ Eiffel Tower, Peru’s Machu Picchu
                     Cambodia's Angkor Wat…. 

    Tier 2: …. lack the global prestige, but are nevertheless significant sites in their regions or country:
                     Italy’s Herculaneum,: Its original wall paintings
                          buried at same time as Pompei was buried.
                     Esoteric Reykjavik, Iceland’s Penis Museum!  
                          (Really)              Really!!! �)  

    Tier 3: IMO, uninteresting, very minor or very niche & not worth average traveler's time & money.
