I love simplicity on the trail. Having less gear is not just about weight for me, it's also about being able to enjoy my surroundings without having to fumble with my gear all day. The less I have between myself and my surroundings, the more connected I feel.
One of the things I've done recently is stopped cooking on trips less than 5 days. It's so liberating to me not to have to cook and clean in the backcountry, plus I lose the weight of cookware. Another thing that's helped a lot is organizing everything carefully in stuff sacks.
Does anyone else have ideas about how to simplify on the trail? I'm not a hard-core minimalist and I do like to have gear to handle any reasonable situation comfortably. I usually bring a tarp, quilt, foam pad, bug netting, minimal clothing (including one insulating piece for most of my body) and raingear, first aid and other emergency supplies (duct tape, rope, knife, etc), and miscellany like sunscreen and *BEEP* trowel.
