Made another trip back this week, the silo itself is still in pretty decent condition and safe to navigate. Although it looks like the property owners are being more active in keeping people out. They only try by blocking the front gate on the road with steel cable and other debris. It is still easy to walk through, I guess its more for blocking cars. Also several more No Trespassing signs posted on the road up.
Unfortunately this time it seemed like someone recently set a fire inside the control room dome, as the top levels were filled up with a large amount of visible smoke.
