One day I was working in a ladies house. Later in the morning she offered me a glass of water. I took a drink and immediately asked her if she got it out of her tap. She said “ Oh no we only use drinking water from the spring on Tyrone Mountain”. She even used that water for the ice cubes. It was really great tasting water. Since then I have used it to make beer and wine as well as some of our drinking water. This place may be busy at times since a lot of people stop here and get water.
The Cache is a little ways above the spring so you have a chance to be nonchalant about searching for the Cache if there are Muggles around. If possible wait until they leave before looking for it. The container is small so BYOP.
This is State Game Lands so you are required to wear Orange during hunting seasons, even though you are close to the road.
