The Athenian Agora. The Agora of Athens was the center of the ancient city: a large, open square where the citizens could assemble for a wide variety of purposes. On any given day the space might be used as a market, or for an election, a dramatic performance, a religious procession, military drill, or athletic competition.
Bear spray is a non-lethal bear deterrent designed to stop aggressive behavior in bears. Its use can reduce human injuries caused by bears and the number of bears killed by people in self-defense.
There is no magic spray or powder or anything else to keep away squirrels. (Squirrel-Repel brand deterrent spray keeps 'em away! Guaranteed!!) Most marketed squirrel repellents are some variant of mothballs or coyote urine. The idea with moth balls is that they make such a bad smell that the animal can't stand to live in the area. The problem is that once a squirrel has found a home, it will work hard to keep it, just to survive.
