Re: [nafex] Water for Freeze Protection and off topic Ice age stuff

["Doreen Howard" <doreenh@ticon.net>]

Donna,
You make a good case for not using water.  I had wondered about it after Dan
wrote that everything turns to ice sculptures with overhead sprinklers in
Florida.  I guess if I was really ingenious or turned loose my engineer
husband, we could rig misters along with fans to keep everything moving.
But, with the weird summer (none to speak of) and this quick advance of late
autumn weather, I'm taking Gordon's advice and packing it in.
Thanks to everyone who had suggestions.  They were appreciated.
Doreen Howard
