Buon giorno, Piero. Pozo farele una domanda? Based on Rome2rio, I can take a bus from Ponte d'Arbia to San Quirico d'Orcia on Sunday , 31 March @ 1809 hr. That seems strange that it would be available on a Sunday. Do you have knowledge of this area? BTW, i was a big fan of Lone Peak shoes (3 Caminos) but have switched to Topo Athletics. seems to be the better shoes at this moment. Grazie, Ciao.
