Boston Transit: A recommendation to get the Zone 1A commuter rail pass instead of the LinkPass...

...from Train Mon, at http://trainmon.blogspot.com/2006/12/zone-1a-read-fine-print-do-detective.html:

By now, after reading a few other's blogs, it seems those chosen few savvy of us, such as myself, who live in the inner-city and inner-suburbs and regularly chose to beat the "rapid" transit bus and subway system by taking the Commuter Rail have come to the realization that, once January hits, the newly minted "Monthly Zone 1A Pass," not a CharlieCard loaded with the "Monthly LinkPass" will be the way to go. This is especially a concern for those of us who get our passes, way a gracious discount, through our prospective employers and have only another week or so to make sure we're getting the right pass for next month.

Train Mon goes through the logic in exhaustive detail.

Discuss.
