Hoping one of you experienced digger could help me out. I have 800 feet of river frontage with a 15ft incline to the river. In just scratching the surface I have been coming up with all kinds of bottles. Also surrounding my property by approx. the same 800ft I have a ridge that goes 25 ft up to abbuting properties. To better clarify this my property of 5 acres sits inbetween the river and ridge. Which is level. Also here on the ridge in scratching the surface I have been retriving all kinds of bottles. In your opinion which would be better to dig for hopefully older bottles.
