On the question of how to place a cache with good coordinates. I've been advised and have done this two times, with success. I have my GPS running from the time I leave the car, pick a spot to hide cache, then log the coords with the push of a button. I then walk away 30 or 40 feet, walk back to the site, record the coords with the push of a button. I do this 7 or 8 times. I go home and average out the last 3 numbers in the coordinates, using them as the final coordinates. Works for me!
