Tucked back behind the pond where there are no muggles to watch. Just beware of the house that backs up behind where this cache is hidden. This is Florida, so of course, there could always be an alligator lurking around, so just be on the look out. More muggle awarness needed than alligators. 
The cache is a small bottle waiting for a friend to find.
