There's a couple that I mountain bike with sometimes and the husband is very nervous about Bears. We ride at our own pace, and since he is faster, he'll always be a little ways ahead of us. Every few minutes we'll hear a "yelp." Its him, making his "big noise" to let the Bear's know we're coming so as not to sneak up on them.

I giggle every time.

On another note, I was road riding a few weeks ago and I saw my first Bobcat! Ran right in front of me and a big descent. Scared the bajeebers out of me.
