You could spend the entire day in the area: immediate > birding, fishing, hiking, paintball, pro-ball, shopping, food, etc., plus several other caches not too far away in several directions.
Now to cache facts:
Around the house ever have something fall or break and you heard yourself say, "if only I had a ______?" Well this somewhat smallish container has a lot of... "if I only hads"...sort of like "round to-its".
Picture hangers, screwdrivers, hooks, etc. Why run to the hardware store when you've got this cache?.
Sort of full, trade something fairly thin. Enjoy the area, the cache will end up being secondary.
