We travel together as a "family unit" (12 legs!), so I carry a day pack with water (lots of water), snacks, small first aid kit, some para cord and a Gerber on pretty much any cahche that will take over an hour. I add contents based on time of day and weather. Yesterday we went to a cache in the early evening, we had enough daylight to complete the cache but I brought along a three D cell flashlight just in case.
