Low flying jet?

[GTO]

Has anybody else seen the low flying private jet flying low over near Blackcat lately. A jet like you'd see landing at Laconia airport. A week ago it flew over me on the lake, made a turn at the Ossipee Range and then got lower and lower flying up the bay towards Blueberry Island, then nosed the plane up again. He then did the same thing a second time. A couple of nights ago, same thing.
