You were definitely in the right spot. All those sinkers,..gotta be some gold around there. Get back there and clean out that spot. I bet you get some yellow.
I am jealous! I still have over 1 foot of ice on our lakes and the surrounding beach sand is frozen solid and covered with snow. Dang.......you might have pulled a few gold on that hunt! Keep up the hard work. Using a PI is not for everyone, but us die-hards!
