I wonder if back, say in the late 60's/early 70's when down started being used, what people said about this confounded new insulating material.... or what folks said about nylon back in the 50's.... "What's with this confounded nylon stuff! My father used a canvas tent and backpack, and his father before that, and darn it, I'm going to keep using canvas until the day I die! (or a broken back, no doubt) REAL outdoorsmen use canvas and wool and beaver pelts ONLY"

I realize this is not a good analogy, but I'm making it anyway.

I do agree ringing cells and talking loudly on them while others are around is bad form, but carrying a cell for camera / kindle reader / backup light / emergency GPS / emergency communication / non-emergency loved-one communication is a fantastic convenience on the trail. Stick it on "airplane mode" and the battery lasts a long time. Amazing devices. We live in a golden age of convenience. But maybe too convenient sometimes? Perhaps.

Enjoy you own hike! I sure do, as much as anyone on here, and with my phone.
