Well, I am very new to this, so most of the ones I have found have been park the car and walk about 400ft or so, so not that much goes with me...just my GPS, pencil and notepad for clues and notes, compass, some small toys to place, and my cellphone. As I get more into it, I will probably start to carry a day pack with some basic first aid stuff, flashlights, water, stuff geared for a full day of geocaching.
