I had a couple of those as well.  As I recall they were either 1 1/4 or 1/2 
at the base and roughly 33' tall. Bout as flexible as a fishing pole, but I 
never had one fail.  Simple, not all that expensive and worked well. arn 
near got electrocuted of one of the ground radials tied to an 8' ground rod 
too. That was before GFIs and a short in a Yaesu FT-101B put the 110 to the 
coax shield. The vertical was far enough from the house electrical ground it 
didn't trip, but it sure did bite!  No that was in the days when few had 
heard of a single point ground let alone used one.

And wait for the ice to melt.  We're on the edge so we don't really know how 
much will be snow, ice, or rain.
OTOH it's supposed to warm up to near 40 with rain and 20 to 30 MPH winds 
tomorrow (Sunday)so there shouldn't be much snow left by nigh fall.
