アメリカのアイダホ州、モンタナ州、ワイオミング州にまたがるイエローストーン国立公園を訪ねていた家族が、思いも寄らぬことを経験した。一頭の大きなアメリカクロクマが、彼らの車のドアを開けたのだ。
YouTubeに投稿された短い動画には、クマが停車中の車の横に歩み寄っているのが写っている。
「父さん、クマが僕たちのすぐそばにいるよ」不安げな声で男の子は言う。
クマは助手席の窓の横に現れ、前の席に座っている男性の顔を覗き込み、難なくドアを開けた。恐怖の叫びが車内にとどろき、助手席の男性はドアを閉めようと必死だ。
動物が人間に接近する例は、これだけではない。2016年のイエローストーンでは、驚くような出来事が続いている。
5月、イエローストーンの観光客が、善意の行動で悲劇を招いた。彼らは、群れからはぐれた生まれたばかりのバイソンをSUV車のトランクに乗せたところ、イエローストーンの職員は、そのバイソンを安楽死させた。数日後に、3人のカナダ人が、イエローストーンにあるグランド・プリズマティック・スプリングの生態学的に貴重な土壌に足を踏み入れたため、刑事責任に問われた。
イエローストーンでは、規則によって訪問者は、バイソン、エルク、オオツノヒツジ、シカ、ムース、そしてコヨーテから少なくとも25ヤード（約23メートル）離れ、 クマとオオカミには少なくとも100ヤード（約90メートル）離れていなければならない。訪問者はまた、道から熊を観察するときは、車を止め車の中に留まることも義務付けられている。
ひとつ助言しよう。車のドアをロックするとさらに開けるのが難しくなる。
