off course

Thinks I to myself, “Sol, you're run off your course again. This is a rich man's summer ‘cottage’ and if you don't look out there's likely to be some nice, lively dog taking an interest in your underpinning.” So I started to back away again into the bushes. But I hadn't backed more'n a couple of yards when I see something so amazing that I couldn't help scooching down behind the bayberries and looking at it.
