re: 3 Day Mt. Rainier Climb- video added to OP

I did this exact same route with IMG in 2011. One of the best things I ever done. It's really tough and yet so rewarding. The views are incredible (pray for good weather) and the sense of accomplishment when you make the summit surpasses most other achievements. We're thinking of doing the climb again in a couple of years as my wife didn't make it to the top.

Good luck and enjoy.
