You are looking for a magnetic, camouflaged small container, containing just a log book.
This cache is placed in a shady spot near a fairly busy, small roundabout that I pass every day on my way to work. The seat goes unnoticed by many and has a natural umbrella provided in the form of a beautiful tree. Parking is available nearby on the street, so can be achieved easily as a cache and dash.
