Moon light over Quarry

We have a lot of quarries in the area that basically supply the country with fertiliser for the fields and stone for the roads. I do like these type of buildings they are utilitarian and stark; very functional. I quite like the lights around the buildings coupled with the moon over the structures.

This was aquickish hand held shot but I would like to do more of these type of images but from within the quarry themselves using a tripod and longer exposure times. I have had some success in the past working from within areas that are often out of bounds usually a polite discussion with site owners etc seems to work :-)
