Okay. We finally found a hiding spot for this travel bug. It didn't make it to Sardinia, but instead booked it south of the border and is now in Oaxaca, Mexico. We don't have a GPS system, so here are the "old school" directions for how to find this travel bug:
The rhino is hidden on Garcia Virgil street, between calles Mario Bravo and Allende, in the historic center of Oaxaca. It is directly ACROSS the street from Casa Oaxaca, at #407 Calle Garcia Virgil. Good luck y buen viaje!
