Lois, upon seeig the scat, I started singing my a very loud list of songs. Some opera, show tunes, etc. LOL Bear bells work in some really remote areas. But, in more human populated trails, they can attract bears. Hikers have been known to toss their packs upon seeing a bear. The bear finds food in the pack and connects the sound of bells with food.
The pepper spray is worth taking with you. We have four cans of the stuff. One in each vehichle and two spares. We don't hike without them. Grizzly bears are common in our area. Sometimes even more than black bear. Pepper spray has stopped charging grizzly. I trust it more than I trust me carrying a gun. Easier to carry and have at the ready, and I don't have to worry about hitting a vital area to stop a bear. There area accounts of a charging grizzly covering over 300 feet AFTER being shot in a "kill" zone. The bear ran even while, for all practical purposes, was dead.
As for the connection between the shrew (rodent) with the shrew woman, maybe someone else here will be able to find the history. LOL For me, being a shrew happens once in a while.
