This is a YouTube oldie, but true goodie. If you've never seen the Battle at Kruger, you should definitely make some time today to check it out. It's an amateur video Jason275 (per YouTube - no idea who this guy is) took while on safari in South Africa's Kruger National Park. It captures a truly epic battle between a pride of lions, a pack of buffalo and a crocodile, all duking it out for one small prize - a baby buffalo. It's an amazing representation of courage, strength, love and perseverance in nature.
(Side note - the video runs for about 8 1/2 minutes, so you really have to invest some time. I know, I know, to think of all the internet browsing you could be doing in 8 minutes. But, I promise you, it's a worthwhile investment.)
