The question: When it comes to Scout Gathering, can they do it in the outskirts of the city?
My guess is "no," though it's not specified in the rule book. The closest it comes to the answer in on page 26: The player declares which of their cities the scout is “sending” the square to during the Start of Turn Phase, and all of the icons in that square (including trade, production, culture, coins, and resources) are then considered to be in that city’s outskirts for the rest of the turn.
I'm thinking that you can't double down on a resourse square either with 2 scouts. But I could be wrong.
Please, someone help me.
