Arthur's Latest Scheme TM is investigating the stock in the shops and restaurants of Sweetwater! He's going to be asking in the diner where they get their fresh ingredients from since he's never had better ones and wants to know where to get them for his wife, when the greengrocers restock so he can come back when his favourite baked beans or whatever are back in stock - basically going to as many locations as possible with obvious out-of-town supplies, asking as innocuously as he can where the supplies come from or when they restock.

At the same time, Numbers and Wrench have been recruited to keep an eye out for any delivery trucks in town; Arthur's using the information he gets to point them to specific shops, but has advised them towards anything with fresh produce, like butchers or greengrocers, or with out-of-town stock again like canned goods from the general store, and advised them to tail any resupply vehicles to try and work out how, or even if, they are capable of leaving the Sweetwater barrier.
