Hi Paul, LF.

A warm coil is no problem, but a failed halyard at the far end is,
especially when a prized porcelean insulator is shattered in the process.
The WX hit again and the RL is on the ground as I discovered this morning 
but it is not known when it came down so the CW last night probably
ended up in the ground via a tree.

The CW will continue tonight for those interested, but at a reduced 
output.
