Rea, a town of fewer than 500 souls, a few handfuls of kilometers south of Pavia, on the right bank of the Po. On June 21, about nine o'clock in the morning we were contacted by  Mr. Mario P. - thank you - by reporting the presence of a crop circle. An equilateral triangle is the centre and with three circles of equal diameter. The entire figure is pretty well done, and is enclosed in a large ring.
