Stifling not so much. There's a few abandoned properties north of the freeway from you but not many big things near you. Unless you go down to Blair and mushroom tunnels
The first shorter tunnel will end with you in lock up lol the razorwire is easy to pass but the cameras, and high security means the owner always ends up chasing you with a torch lol the second long tunnel is do able, well was a bit over a year ago.. If you google it won't take long to find
Also check out the old train line that went through mount barker - Some of those stations are kinda cool - There are a lot of old churches as well, and some cool stuff up and down the freeway
