Here's some stuff that increased my enjoyment of the rockies this summer--
1) Aquamira Frontier Pro--
This is ended up saving me a ton of weight--with abundant (and familiar) water sources, I was able to save lbs off of my pack weight on both backcountry trips and day hikes. I'd just carry this in my hipbelt pocket with a liter palypus wrapped around it and only drink at water sources. For long trail runs I'd use this setup with a few gels and a windshirt in a montbell lumbar pack which was little more than a belt with small pockets.
2) Bear Valley Pemican Bars smeared with Peanut butter--this was a hearty enough combo to allow me to leave my stove at home for fast/high mileage trips. I usually forgot about my hunger even half way through one of these dense food bars. They also have the morale boosting bonus of tasting sort of gritty and wholesome like something a cowboy would eat on the trail. At $1.50 (and often $1) on sale, the price was right and I don't remember seeing any bars that had more cals/oz.
3) Droid X (smartphone)
I know this goes against a lot of 'backcountry philosophy', but these days I'm all for integration over escapism. At about 5oz, I had a camera (still and video), advanced mapping with gps, books--written or audio, music (although I saved this for rare occasions like the last 3000 ft pass of a 30 mile day when I needed a little escapism :), journaling, a better way to research/plan trips in mountain towns without having to bring my laptop....the list goes on of course. Probably the best part was when I'd see my friends around town I could share high quality pics and video from my trips on the spot. A good way to get folks excited about the mountains.
BTW, Craig, that is an amazing picture!
