Greyhounds in Flight

I accompanied my mother on a lure coursing trip with her dog, Houston. There, we witnessed some Greyhounds and Whippets running the lure course (which consists of a plastic garbage bag connected to a long string which, through a series of pulleys driven into the ground, leads the dogs through a winding course in a large field). I’m not sure who had more fun, the dogs running the course or the owners watching!!
