I have been eavesdropping on your e-mail to Charlie (like a diligent Ziner should) and have found your input very helpful.

This may be a foolish question, but, is the Mobilis pass available at tobacconists as is the carnet, or only from Metro ticket booths? Also can you purchase them in advance from home?

If available here, should I presume that the relevant web page is in French only?

Best regards, Don in L.A.
