That is what I am doing, as I have just written in the post above, I', having bad rng when fishing as well.Sorry I guess I miss read. Anyway if you are worried about resources then try fishing. It recently got a revamp that allows for fish and resources that can be sold for money. Fish have the highest priority when it comes to food so if you are trying to save your fresh food for a garden that can help. As for why you are not getting any, it sounds like you have had some bad RNG.
What I like to do is to try and get all the resource spots on the same cycle and loot them all at the same time. Since you can use the bus stop you can hit every area in one run, so it doesn't waste to much time.
Oh well, doing the quest to go to the underground now, so that should alleviate it.
Guess my 40+ water is coming in handy
