A thought on the IL Alternate 3:
This alternate is really hard. However, I noticed everyone was creating a solution with access from the RBO to SO. I know that in the other programs, it is stated the RBO has direct access to all spaces, and this Program does not. So, since nowhere does the Program say that RBO has to have access to SO, and since SO has access to LCR, could it be taken that SO doesn't need access to RBO?
Just wondering people's thoughts since I have always been told not to read anything into the Program that isn't there.
