Actually I came up with a good solution to my problem today, although I appreciate the suggestions
I work at two labs and one of them is in a less developed area and I found out today that the grays like to hang around the edge of the liner to the water garden at the aquaculture demonstration facility and that they sometimes get inside the building, so from now on all trespassers will be forced to come home with me. Also my assistant told me friends of his often have them under the lip of thier pool.
How far North am I you ask?
Far enough that Canada isn't a long drive from here and digging my car out of the snow bank is necessary even in April at times!
