I gave up on Boston...the Houlton Maine crossing on I-95 has appointments three days a week Tu-Th in the Woodstock (Belleville) NB customs warehouse just over the border in Canada. Multiple appointment times open the rest of August each of the three days each week. 5 hours up from Boston..not great but wife's GOES expires in February so at least we get it renewed before the expiration.

And I thought starting the renewal seven months ahead of time would be fine for a Logan appointment!

But, yes, something seriously wrong with this setup that even people starting so far ahead of time have to take off work and drive 10 hours to get an interview.
