Coyotes. Need to hit Cabela before you go biking. Pickup one of those coyote calls, 22 shells, and small 22 rifle. Or camping small zapper electric fence. Charged by solar (at camping stores). They work good. Bait the fence and coyote will lick the fence ,and wham he gets little jolt energy pumped into him. Then they are gone for good. Works for bears also. Coyotes are harmless, however they search for rabbits, birds, and domestic animals is ongoing. Feel sorry for people whom lose there cat or dog near coyotes. They don’t have a chance. Good luck.
