At present it's in the carport next to my car. What if it's still there when I need to go out later? Or worse - what if it's not? And has got up into the undercarriage of my car and makes its way inside? My head says it's not actually possible but my hind-brain says There's Gaps! It Could!
In any event my plans to spend most of the day in the garden have been shot to pieces. No way while there's a freaking snake about.
