Mark,

If you have the time, you could take the train from Fiumicino to Viterbo, about 2 hours. Rent an auto at Viterbo and take the scenic route to Florance, visiting the hill towns along the way, Cortona, Gubbio, Montaicino, Montepuiciano, San Gimignano, Todi, Volterra to name a few.
Do you speak the language? Poke around and you will find some small gun shops.


Good Shooting
