It's ok to be just running at it blind because that is what I have done. I have had a great time and found some really great hones and a lot of hone shaped rocks. For me I use what I would call a brute force attack. I just keep looking and testing. I have some areas that I can go to that yield quite nice hones but for me my exploration is not done. There is always more to see and find. I was out last weekend and got a bunch of rock. When I get a chance I will spend a weekend cutting it and many evenings lapping and honing. If nothing else it keeps me out of the bar.
