While visiting the Appian Way in Rome I noticed the archeobus. I assume there may have been a guide with the group at the Tomb of Caecilia Metella. That is a neat idea on a dry day.
Perhaps the next time I am in Rome I will look into this tour. Photographers were utilizing the beautiful sunny day and the ancient ruins to photograph some newly weds (to be?).
I wondered if they knew that the Apostle Paul once passed this way (Acts 28).
