Most places like this one wouldn't ever tell you to BYOB (Bring Your Own Bottle) but it's exactly what you'll need to get this cache. One half gallon should be enough. Although it is possible to do it solo, it will more fun with a friend.
This is a daytime only cache, on private property, placed with permission of the nearby establishment. Kids will have fun too.
