Thanks to everyone for all the kind words.
Fang, I'll try to get out again in the next several weeks to see if I can establish a better location. I was trolling so a GPS waypoint wouldn't give me an accurate spot. It is however a small lake and I have a pretty good idea where I got them. I'll be bringing my depth finder next trip and try jigging - if successful then take a GPS reading for ice fishing purposes (if I actually take up ice fishing). Appreciate your advice.
Thanks,
Barn
