What I carry depends where the cache is located in an urban area where I can get close to a cache with my vehicle I just carry the GPSr,a compass, and a pen and some trade items in my pocket. On more rural hikes of a 1/2 mile or more I have a small daypack with water, snacks, TP, maps, GPSr, camera, cell phone binoculars, flashlight, compass, extra batteries, bug spray, first aid kit, matches, space blanket an assortment of swag, my rubber stamp and ink pad. I also have extra pens and pencils some extra plastic bags, and some duct tape. I also may carry a rain poncho or handwarmers depending on the season. On a longer day hike I may take a penny stove with fuel and a pot to heat some water for a small meal or coffee or tea. Certain items are added or taken out, as a cache decription maybe there is a lake or stream nearby I will add a fishing rod and gear to do some fishing. The idea is to customize your pack to each hike. Over time you get rid of some items and add new ones. Thats some of the fun.
