Sub-Roof?
So I was out scouting an object today. I obviously won't go in to detail about what/where, etc... but it's a B. On the floor below the roof access hatch there's a door labeled "sub-roof." I didn't have the ability at the time to open it, but I'm thinking (from rudimentary imaging on Google Earth and a bit of logic) that there are 2 levels on top of the building open to the sky: The roof and the sub-roof. This would seem to make sense as the sub-roof was a door and the roof was a hatch. So my questions to those who might have more knowledge of B's are these: Is that assumption likely correct? If so, once on the sub-roof do you think there will be some variety of access (ladder/stairs) on to the "roof-roof"? Thanks guys and gals.
PS: This is obviously a sensitive subject, so I've created an anonymous BJ.com account so as not to give away my location, etc... I'm really sorry if this offends anyone, as I believe it's technically against the rules. If anyone doesn't feel comfortable responding in the public forum, please PM me and we can converse by email or phone. Thanks again for your help all, I'm really interested in this object.
