At the information centre I went to (three are listed) and from enquiries I had made from Australia, it was apparent that L'Aquila was looking for tourists. The proffering of seemingly endless maps and information indicated that.
I reflected that, in places like Sienna and Florence, everything has a price and they've had tourists up to their ears. Here, the smiles and welcoming gestures are still readily apparent, a reminder of why I wax lyrical about venues such as L'Aquila, Trento and Vicenza. They still value their clientele and have time to spend with you. Thus it was that, armed with maps in hand, I wandered back down the narrow via Leosini and walked past this sign. It's one of those things you go past and think "I should've taken a photo of that". Many times you don't take the trouble to stop, unload all your gear and make the effort; but this one was too tempting. I think the reasons are self explanatory.
