 friends and former neighbors Jim and Dianne Lanasa at
 their home on The Outer Banks of North Carolina.

 To add to the pleasure of the visit, six meters opened up
 all three days that we were there. What excitement to put
 out an "N3NBT / 4 in FM25" then release the key and
 have a pile up. As I responded to the calls, Jim did the
