We also fished back in the 80s and 90s casting mainly west of bass islands.We became friends with a charter in our marina.He gave us a laminated paper that had numbers for like 40 locations that only a few people knew.When we were out fishing we could only communicate with radio.So captain would radio us that catching well 2 miles north of #5.That paper said #5 was Niagara reef.So off we would go to try and find him.Only had compass,chart and radio.Eventually we got lorance unit for location help.How things have changed.
