Driving to Sister's today to stage a car at McKenzie Pass. We stopped in Bend to replace my hiking pole tips and found a great deal on a Big Agnes air mattress at REI. My old Z-rest pad is definitely worn out. Loyd, an amazing 70+ year old trail angel from Bend, drove us from Mckenzie Pass back to Elk Lake so that Sybille and I could hike together through the Three Sisters Wilderness. He had great stories including a description of the Ring of Fire where he knew all the tongue twister names of the mountains. After lunch and a beer to toast my birthday at Elk Lake we hiked seven miles to Sisters Mirror Lake.
