Locked up

These locks are part of the winch that I've blipped before. For some reason, I'm seeing locks everywhere. I like this because there are two locks close together.
Might be the start of a series.
G and I spent several frustrating hours trying to figure out how to listen to tv programs through our stereo system. It used to work, then we got a new satellite receiver about a year ago and it hasn't worked since. I'm usually pretty good at figuring this stuff out but we've both tried everything we can think of . Now we're waiting for an "expert" to come to see if he can figure it out. I reckon it will probably be something simple that we should have twigged onto. We'll see.
