You are looking for a small 1.5 pint rubbermaid container. Photo shows container, next to golf ball for size comparison.
Relatively urban area, using smaller container, please keep the exchange items on the smaller side.
Cache is less than 1/4 mile from parking lot. Nice park, surprisingly large. Park has been mostly rural for years, but the urban sprawl is slowly approaching. I disturbed a hawk while placing the cache. Saw lots of birds, and even saw where a beaver once lived in the area.
