Alien spacecraft

I was taking a photo of the rainbow through a closed, double glazed window and it conjured up some alien spaceships ha ha.
Been a hot and humid day again with a torrential downpour shortly before I took this photo.
I have been invited to construct an adventure lab cache (sorry to those people not understanding what that is) which has pleased me and I have already chosen my 5 locations. Tomorrow I will be visiting them to take coordinates and formulate questions. That is if the weather allows it - looks like it could be bad but we'll see.
