Sure they couldve added a few more havestables in the bramble woods (personally I never had any problems finding what I needed tho) but other than that, what else would one do when in the woods/country?
Maybe bird watching...and if the picknic basket would actually let us have a picknic on the ground that would've been cool...
That rabbits and bird trees are limited makes sense to me, irl rabbits run and hide from you, they maybe there but you wont see them, birds are flying or up in a tree not directly in front of you being able to be talked to ;)
What would really be cool if we could hike there, like we can in Mt Komorebi, especially hike with other sims (and dogs).
But you can cloudgaze, take photographs, walk/jog with your dog, play with/train your dog, maybe do yoga if you bring a mat, picknic at the picknic table, pick harvestables, swim in the river, look for frogs, talk to birds and bunnies, watch foxes, go fishing, investigate the snail statue, interact with the creature keeper (talk, buy, trade and order animal clothes)...I feel like that is sufficiant for a rural area.
