Welcome to the Board HappyHunter! I too have had great success with leeches in Canada and Wisconsin. This year the only place I found some locally was at Wally World for about a 6 to 8 week period. I had some success with them at Nolin using a Lindy no snag slip sinker rig and a gum drop floater on a 4 foot leader. This was the first year that I have been able to find leeches, but it was late in the "leech" season so will now have to wait till next year. I an now looking to find some large 4" to 6" minnows or creek chubs for fall, cooler water eyes.
