Rangers in several of the national parks we visited told us to be on the watch for charismatic megafauna...the big ones being bear, elk, coyote and cougar.
During the course of our trip, we saw three of the four - (no cougars, thankfully). This mama bear and her baby cub were a surprise in Sequoia National Park. I had just one shot. It's a little blurry...the bears were about 10 feet away and I was hoping they didn't notice me, noticing them. They didn't seem too troubled by our presence.
