Dodgy CL results-- Advice?

Ya thats a tough spot to be in. The crap thing is, it could be all over their place and animals with no outward evidence of it. At great cost to you, you could put up another fence along that property 5 or 10 feet inward to give a lane so they cant touch. But if the wind blows from that direction to bring the infected dirt over to your side, or their dog comes over to your goats or even your dog after being in an infected area...
