I completed my 4 day hike in the Three Sisters Wilderness in Oregon's Cascades, but didn't make it all of the way around the loop due to logistical issues. I did ~46.5 miles in four days. The weather forecast called for 75F/45F and sunny weather, but we got 60F/35F and overcast, so we didn't get the great 50 mile views but we still enjoyed the lava flows, cinder fields, hemlock forests, rainbows, glaciers, and occasional views of peak or two. Andrew Skurka mentioned on his podcast that he thought this section of his Great Western Loop that this was the highlight of his trip up to that point.
I let my brother, who is at the lighter end of a traditional backpacker, carry my pack while I carrier his REI "Ultralight" pack for several miles. Although I'm not sure if I converted him to a true UL hiker, he did appreciate some of the options. We slepted under my Oware 8x10 Silnylon tarp, used Aqua Mira, and cooked with my brand new Caldera Cone. I was plenty warm with my Oware Bivy and Jacks R Better No Snivler quilt. I think I could have left my Mountain Hardwear down jacket at home and used my No Snivler around camp, but ti did make an awfully nice pillow.
I put my photos on flickr. You can get the captions by clicking on the center of the photo. While you are in flickr, you can search for some really good photos by better photographers, who have better cameras than me. Here's the link and a few photos from the trip.
