Ugh. I just don't see a polite way for this to be addressed. I thought maybe I would ask, "whose fence is this? And, do you mind if I put up a privacy fence?" They would ask why, and I would explain. Sad thing is, it will look t-a-c-k-y. I did think about making a 'dummy' fence, with something stronger then chicken coop wire, and staking it about 3 feet from the fence line.

Guess I will have to talk to them and just take it as it comes.

Thanks!
