Hey Mark , My wife found this " crawler caller" in a clearance isle at wal mart. I had it in my tackle box for a few years never thinking much of it. When spring came around and I started buying nightcrawlers at gas stations, bait shops ext, at about 4$ a dozen. I thought I would try this stuff "crawler caller" out. Its freaking amazing !! Like you said worms galore !!! In the middle of the day no less. But my problem is now I can't find it anywhere ! I've called Bait shops, Rual King, Farm & Fleet, Gander Mountain, Bass Pro shops and Wal mart. No luck ! Can you tell me where I can get this stuff? Ha, I even told my wife I am going to start my own nightcrawler buisness after using this product. Help me out please? Thanks my fellow fisherman !!!
