...doesn't mean I know about all things electronic. Take GDO's. I don't know JS about GDO's. They either work or they don't. I can't take one that doesn't work and make it work. For that I have to call in the professionals who have some secret device on their service vehicle that makes any non-functioning GDO become a functioning GDO when they approach within say 25 feet.
So tonight I go to Bonnie's and plug in the GDO, unlatch the vacation latch, reconnect the chain to the door arm. Press remote. Door goes up, door goes down. Again. Door goes up, door goes down. Again. Door goes up, door goes down. You get the picture. I did nothing except plug the GD GDO back into the power receptacle and today it works. Repeatedly.
Bonnie mentioned that she would have a sight seeing day this week in which she would go to Hangzhou where there is apparently a beautiful lake. So I did some surfing to see where she would be and this is one of the pictures I came up with. The caption totally cracks me up.
