If you are considering doing some camping this summer, please note the following public service
announcement: 
In Alaska, tourists are warned to wear tiny bells on their clothing when hiking in bear
country. 
The bells warn away MOST bears (brown, black, etc.), but be careful because they don't scare 
Grizzly Bears. 
Tourists are cautioned to watch the ground on the trail, paying particular attention to bear 
droppings to be alert for the presence of Grizzly Bears. 
One can easily spot a Grizzly dropping because it has tiny bells in it.
