Missing pony Canandaigua, NY

Left her paddock between 8 and 10 this am. Dark bay, large pony mare, named Beau. We have done all kinds of searches-the latest being on horseback, and have only found hoofprints, along County Rd 32, to the corner of Woolhouse, then lost them. This is a little girls 4-h pony-lets all hope we find her safe. And-in the meantime-ALL DRIVE CAREFULLY! Dark pony+night=danger!
