In my area we are very community minded. The population is mostly 20 to 30 year olds. The elderly are very active. What would be the best for trade here is means of extra warmth and collapsed water carriers.
Batteries would also be useful. What I feel people would want first though is food and alcohol. These Would be scarce for most families as we do community dinners in the winter to help the residents. It is tough here in the winters for a lot of people.
