We had another of the landscapers meet with us this morning. She seemed very nice and very thorough (though GF had provided detailed designs and a document explaining the brief). We just need to wait for her quotes to come through.
The stiff neck is problematic. GF has almost no rotation to left or right. The problem is made more ridiculous by his varifocal glasses. These, of course, have a sweet spot in the middle of the lens and in order for things to be in focus you need to look through this sweet spot. This means that GF relies on head rotation to see things clearly. Today he has to do complete body rotation.
