The Lee Rd. spotting area is fairly good IMO. Cops and others often frequent the area, so I wouldn't be afraid of too much around there. I don't think I would go there if it looked COMPLETELY deserted though.
You can also check an area by off near Greens Road, by the western-most runway(forgot the #), there is another great spotting opportunity, though it's mainly takeoffs.
Oh, and you may just possibly get a little sick of seeing CO!
