Topband: cattle-proofing

[n5ot@n5ot.com]

I am building beverages that have to withstand cattle-running on the property (i.e. no sloping wires, high clearance, steel supports).  Any tips/caveats from those who've been there and done it?  

Problems I anticipate:

1. Getting good grounds in soil-over-sandstone
2. Vertical down-leads that don't mess up the pattern

What other problems should I anticipate besides how rough the cows will be on it - I think I have that one under control.

Any problem using #13 Electric fence wire?

Thanks in advance.
