When we bought the house, we knew that we'd eventually need to replace part of the fence. The fence on one side and most of the back of the yard was fine...it was obviously put up by someone who had some idea of what they were doing. However, the other side...not so much. The fence was shorter over there, and pieces of it were falling off. Oh, and there's one section of the back of our yard that was never technically fenced in. There was just a temporary "wood and wire" fence put up.
Here's an example of the fence between the yards:
Happily, these neighbors are awesome. They very quickly agreed that the fence would need to be replaced, and rather than hire someone to do it, they'd love to just chip in on the cost of it with us, and the guys could do the work themselves. Woo hoo!
A few months passed before the guys got started on it. And frankly...it took awhile. Fortunately, Jeff and Emma like Satchel, and they were totally okay with letting him have full run of our combined back yards while the fence was down.
Here's are a couple "in progress" shots:
