I just ran out to the garage as I have a container of leeches in the gulp alive sitting in the boat from the summer
It was not frozen at all??? -20 outside too???
Anyway I like the Leeches for spring walleye on worm harness. When you are trolling for eyes and the perch start stealing your bait. These work great. I like the 5" which are hard to find.
As for hard water. Im going to bring some shinners out to the BOQ this weekend along with some muds and see what happens? If anything it will be somthing differnt for the fish to look at.
BTW - I purchased 2 of the baged minnows and placed them into a old container of alive liquid from summer. cheaper and I get a mix of sizes too.
