Still trying to get a hold of what is going on, This groung radar sound like a good idea espicall if it could take the place of gigging test holes. So far the smale model you describe has not been around here, but still looking.
As far as bedrock. When you dig and hit the rock stop digging and cover the rock with two feet of clay. be sure and pack the dirt.
Sometimes mother nature will not allow us to get everything we want without spending more money that the place is worth.
