Great idea! I will try the 1/2" poly tape as a divider for the visibility.  Cows are not the problem. In fact that fence was so hot and fresh in their memory that they would not cross the line even when the fence was down.

The much more visible polytape would also be much easier to handle as a divider. I think of poly as a horse thing but maybe it would help with the deer. Should not be any problem with the cattle, won't use it with the rent-a-bull.  I'll give it a try. Thank you for the idea.
