Hi, GoulaisGirl! I'm not that far from you -- near Sudbury. For the horseforum and Northern Ontario that's pretty close. :) Our snow here is deteriorating quickly. You'll be not far behind! But you get the lake effect; lucky you.
BTW, they can't just walk out unless the snow is well packed on both sides of the fence. They'd get bound up in the deep snow. But, we had a good one here. My hubby decided when he plowed once, to just plow up to the fence, instead of opening the gate and going beyond as usual. We ended up with a four foot snowbank with the fence buried in the top of it! Yikes. I had to shovel that out and told MDH no more of that please :)
