"Join Sam Adams at the meeting" is an objective during the mission On Johnson's Trail during Sequence 6
Optional Objective[edit]
Stay below Notoriety level 2
Walkthrough[edit]
Connor is off again to meet with Sam Adams. There will be a few Tax Collectors on your path. Ignore them for now as they will spike your notoriety if you engage them. Just pass them by until you complete the optional objective to keep your notoriety low.
With that in mind make for the marker to once again find Samuel Adams. Arrive at the destination and go inside the house to move things forward with the next cutscene.
