So, if the first point is a place where you could see the fire tack (for instance); that would not be a physical stage and no minimum distance is required.
Cache containers and physical stages should generally be separated by a minimum of 0.1 miles (528 feet or 161 m). A physical stage is defined as any stage that contains a physical element placed by the geocache owner, such as a tag with the next set of coordinates or a container. Non-physical caches or stages including reference points, trailhead/parking coordinates and question to answer waypoints are exempt from this guideline.
Additionally, within a single multi-cache or mystery/puzzle cache, there is no minimum required distance between physical elements.
The farmer gave permission to place the cache in the field, but the bull charges.
