Thanks for the info....yes...planning is a plus. I have mapped out many casinos...even though I might not be able to reach them. I have also figured out where some of the Numismatic shops are. I signed up for eBay France...so I could communicate with sellers...but also to try and figure out which seller live in towns close to the places I’m visiting. Some of them have brick and mortar shops too.
Monaco has a rally race the 24-28.... so I expect it to be busy and might keep away during those days.
Do you know if Carlos Pasacoal lives in France? And where if he does? I wouldn’t mind trying to get a chip from each place I visited. I see on the ChipGuide he has submitted many of the chips.
