Yesterday I had two White-winged Crossbills fly over Old Crane Highway
north of Marlboro Pike.  There are lots of Spruces and Hemlocks in the
area so I have stopped there several times and finally got lucky.  Where
I found them there is a good paved area to pull off the road near some
mailboxes, but there are others spruces in the area as well.
