2-mile out of Lakeside

[ducktrapper]

After almost 30 years of springtime slip bobber fishing on Lakeside Reef, I saw something last week that I had never seen before. During the day, every boat I could see on the lake was parked on that 25 foot deep structure called 2-mile, about a mile west of the Lakeside rocks. This included launches and people waiting for the evening bite to start. I've fished it before, but never saw this many people keyed on it. It made me wonder: what makes up this structure? Is it rock, gravel, or ??? You'd think after 30 years I would have found out, but honestly I never see more than a few people on it, never paid much attention to it.
