Many players seem to be unaware of the fact that you can trade 1x Stone for 1x Wood in My Time At Portia. This is a great trade, especially in the early game when you have lots of Stone, but typically also need a lot more Wood than you can easily get your hands on. So by trading your Stone for Wood, you get to save all those trees from being chopped down, and you also save yourself some time in the process.
In order to trade Stone for Wood, go to A&G Construction. Interact with the table to the right of Gusts to trade. There is a daily limit of 999 trades, but you can easily just wait to a new day to trade more if you need it.
