Tony and others,
Received this a few days ago. Bill Evans knows ALL about towers all over
North America. He's also very co-operative and helpful, should you want to
write to him.

c) The extent of efforts to reduce the threat to migrant birds
PLEASE ASSIST IN THIS EFFORT BY ANSWERING THE QUESTIONS BELOW
