In one game save, I built big’ol bases in the first red ant hill by the oak tree. You can’t it anymore cuz land rights were taken away, but it was. Just had to squash the red soldier ants when they spawned.
later in gameplay, I took over the wolf spider den under the oak tree. Every few days there would be some unwanted visitors waiting in there… nothing a little spicy dice couldn’t handle
I haven’t checked to see if you can still do that or not. The best move for transportation is to climb up to the mushroom ledges on the oak tree and build a platform to have one zip line for n either side of the tree. Payback can’t get you up there. Had many bases up there too.
