not too tough to move if there is a good location for them, screw bolts 
will do it.

Your right, jumping across the legs so they only present 110v is the 
safest answer.

good thing about the ceiling is all the rough cut 2x12 structure, its 
easy to fasten to so we can move the fixtures pretty easily, compared to 
concrete or sheet metal studs) Best to get some of those wire hanging 
bolts that screw in with a drill. Makes it real simple. (I'll show you 
next time we cross paths.)

They further concluded that at least 8 detainees in US custody were 
tortured to death. Steven Miles, reporting in this journal, put the 
number of deaths due to torture at 17, with 11 cases occurring in Iraq 
and 6 occurring in Afghanistan.[8] 
<http://www.pubmedcentral.nih.gov/articlerender.fcgi?artid=1868355#R8> 
Many of these deaths involved torture or abuse related to harsh 
interrogations of the detainees by US personnel.
