I was the webmaster for SBISC, and a longtime member. Last time I saw the building, it was vacant and for sale. (It was leased by the range, not owned.) I occasionally talk to the former manager, and have heard nothing about any plans to reopen.
It's a shame too, as it was indeed a very nice place to shoot. 4-time USPSA Open Division champion Max Michel grew up shooting there, and his dad, himself a USPSA Master shooter, worked there.
I leave the SBISC website up as a memorial.
I shot quite a few of the friday night plate matches there. Greg, If you see Ray, tell him the Miculek's say hello.
