PICS OR IT DIDN'T HAPPEN, PERIOD!
I stalked this Grizzly Bear for a couple of hours trying to get some good shots. He'd go to one place and I'd circle around to a spot where I thought I'd get a good shot. When I got there he'd be gone. We played this cat and mouse game for a few hours. When he finally layed down I had an opportunity to get into position to take this photo. I shot some good pics and just sat there and admired this animal for about 30 minutes. When he started showing signs of agitation I decided it was time to leave. I stood up and started backing away from him, in the process of walking backward I tripped over a log and fell flat on my back, which triggered his prey instinct and it was game on!
He immediately got up and charged me full speed. I managed to get to my feet before he got to me and I just stood there and held my ground with this 300lb Grizzly Bear running full speed at me. I couldn't believe how fast he covered the distance between us. He was so close I thought he was about to tackle me to the ground but instead he skidded to a stop less than 10ft from me. He stood on his hind feet, towering over me, and let out a huge growl. Once back on all fours we had a stand off for what felt like an eternity but it was probably more like 5 minutes. I wasn't about to move an inch and trigger his prey instinct again. So we both just stood there, he was so close I could hear ever breath, see every nostril flair, and smell every scent. Finally, he just turned and walked away like it was no big deal.
Definitely in my top 10 adrenaline rushes for sure!
