I remember those days!! We didn't have gps or a fish finder back then. Grandpa just had an orange​ jug with heavy line and a big weight on the bottom,we threw that out to mark the top of our drift! He used the compass and cans to navigate. That's how I learned to run a boat. I remember his first gps. We all looked at it in amazement lol. I'm digging out the ol Erie dearies and golden nuggets! .. FISH ON!
