hi, we just bought property near Fort Smith Arkansas. There is a cave on the property, how big it is I don't know but the previous owner said it goes in about a half an acre. When looking at it we had no good light and so we only went in the front of the cave. Once we start moving out there I want to go in and explore it and basically make sure it is safe (we have kids) and maybe use it for a peaceful place to go. You guys are the experts so can you give me any advice on how to go about checking it out? I don't even know if it would be considered a cave or a hole in the ground or a cavern or what.
