Looking at making this same trip/connection and glad to hear that a BBY sleeper ticket still gets one access to the CA at BOS.
However in the time that's passed it looks like ARROW now forces one to take Downeaster 680 rather than 682 to make this connection which results in a 5 hour layover...
Now I can post with my account. I would be interested in the companion pass for a trip on the Downeaster I'm planning to take with my girlfriend. Feel free to contact me at sicariis at yahoo.com Thanks.
