If moose 'look over the fence' and take that much notice, they will go right through it unfortunately. It is not a guarantee, just a deterrent. Not much stops a moose if he is determined. I have seen pictures of moose with fencing all balled up in their horns where they bulldozed there way in but couldn't get loose from the wiring and such.
Our ground is frozen down about 1-2" and I don't think it will thaw out much during the day,. It is 40F here with clear skies. Really nice if you are dressed warmly. I had to work out in the botanical gardens today and couldn't wear gloves for what I was doing (not digging in the dirt - placing signs, wiring some to woody plants) and my fingertips about fell off. lol
