Used to go out with an ole fella when I was younger, he was a twitcher an took me a load a cool spots, but we went up to a Forrest blocks up the back end of measteg an watched night jars regular, best time was as it was gettin dark, an he would wave a white hanky an they would come in real close whizzingpast is thinking it was another nightjar. Funny noise they make, like a whirring machine or summat, hard to describe, amazing to see tho
