This idea could be implemented in a number of ways.
The aim
To make community trading feasible, community specialization practical.
implementation
one possible idea is to use wagons or something like this. fast travel wouldn't actually be fast, it should take x number of hours to complete a trip. 3-6-12-24 hours? it could work somewhat like attuning a key where the wagon would have to be manualy brought from point a to point b. once a route is established the fully loaded wagon can travel on its own to its destination.
As it stands town claims really don't function like real towns, it would be great imo if incentives were created to necesitate town hubs/ trading centres other than just boston.
i'm sure this isn't a new idea, something along these lines has been brought up before but its been a while, so with new players mayby some new ideas.
tired of alt porting all my junk to boston and back to homestead
