Thanks for the info. I'm always curious about structure. It's pretty cool to see multiple species in one spot. I caught 5 species out of one hole last week. (yellow perch, crappie, bluegill, sunfish, largemouth) I don't think it had anything to do with the spot, but it sure was fun. I'm hoping for the least amount of snow possible from the storm this week. It just make access for difficult. Good luck out there!
