I went up with my dad a few times and once with my brother and dad. I was 14-17 years old. We drove from central Bucks Co. to the northern most part of La Verendrye then 9-15 miles west back dirt roads.
We sometimes fished out of a motor boat and sometimes out of a canoe, depending on the size of the lake. There were scores of walleye, many small to medium sized pike, and the occasional monster pike. We watched native folk snare sturgeon in rivers and paddled up on moose feeding in shallows. And, we rarely saw another person.
It was a fantastic experience.
My memories are still vivid.
