The wolverine was near Stanley, Idaho, last June. The photo is somewhere here on BPL.
A ringtail cat would be nice. That's on my target list.
You can buy the jingle bells in different sizes, but the assorted bag gave me the most flexibility. The tiny bells are lighter in weight, but the bigger bells are louder. As a result, I made my string of them with different sizes.
If I am lazy, I just pile the bells on top of my bear canister. Normally if I think critters are really around, I will tape one end to the top of the bear canister and the other end to something on my shelter. So, I may hear the bells, or I may feel some vibration. You can also put all of your metal stuff (mug, spoon, etc.) on top of the bear canister, and it will fall over when nudged by the critters. But, you have to have your camera all laid out and ready to fire.
