Thank you all for the replies.
Philip.......The website showing cities and towns with ZTL is great. I hadn't run across that before. It looks as though we should be minimally impacted. I figured Alba would have a ZTL for sure. But, I had scouted out the parking options which seems to be plentiful just outside the city center.
Nigel......thanks for the heads up. I hadn't heard they have toll roads with no toll booths. I figured they may have unattended exits here and there. But, I have a chip and PIN credit card I was hoping might work at an automated booth. I'll look on the Autostrade website and see if I can find details.
Frank....most helpful, too. I've been reviewing traffic signs routinely and involved my wife to help recognize the signs for ZTL. After reading all the experiences of people driving in Italy, I'm taking the challenge not to get traffic violations in the mailbox months later! LOL.
