Bull Spring?
It can be amusing, all right. The field enroute to Lasham from Booker that I decided looked landable was lined with trees and shadows. Under the trees the shadows included about 50 black yearling bulls. Entire bulls.
Of course they thought I had landed to bring them lunch. I spent the next half hour running round the glider trying to keep it intact. At last a farmer driving by noticed my difficulty and brought his Landrover round to help move the glider into the next field.
We used to raise polled Hereford bulls on our farm in Devon, years ago.
