So i just dove Spiegel Grove which I have been on many times. Who monitors the entrance and exits of this wreck? and most importantly who has chained off some of the entry/exit points. This is a huge hazard. I was coming up from one of the lower decks to find I was trapped because one of the exit points was chained shut. I went back the way I had came and found a chain with a lock on it on the outside hatch. This is a huge danger and should be removed before it gets someone trapped and hurt. Well i'm just looking for who would do something so stupid as to chain shut exit points. thank you
