I've gone through several iterations of prison design so far, and it seems the only need that ever gets satisfied in the Yard is Exercise. Can that need be fulfilled with the use of a weight bench or others objects, without having to send the prisoners outside? If I could get rid of my yard, without the prisoners suffering, I'd rather do that, which would save me some logistical headaches. If not, it's not a huge deal, but I'd like to get a little more creative with how I lay things out.
Speaking of weight benches, I've never actually seen an inmate use one directly, which I would assume looks like them standing over it. I have several in my existing yard, but they seem largely ignored. Any idea why this would be? Or is it that their presence is enough to fulfill the need?
