Thanks for the comments, everyone. It is a site that I'm sure I will be revisiting many times.
I don't know if I will be able to detect any more this year or not since winter seems to have arrived early. If not, this site will still be there come spring.
As I was logging my finds today I realized that I have now found exactly 500 silver coins with my E-Trac. This was my 4th year with it, I bought it in February of 2011. To say that I am impressed with this machine's performance is a serious understatement. To think that I hadn't found a single Seated Liberty coin before I got this machine, and now I have found 17 of them. I never would have believed it could be possible. I love this hobby!
