One rather 'grey' day under the Lesner Bridge, the stripers were boiling, then as a boater would try to reach 'em, they'd leave, and then within 20 mins. they'd come back, sticking close to the boat channel. A couple of us guys on the bank were trying to reach the fish with 2 oz. spoons and/or hopkins, stingsilvers, whatever...
...anyway, someone came up to where we were all wading, and tied on his topwater plug (it was a Zara Spook-HUGE! I made sure to ask about what he was using.) and started to 'walk the dog'. It was exciting to say the least, to watch this guy not be able to cast as far as I could, but have his strike be so visible as the stripers would try to hit his lure. He didn't have hookups on every cast or anything that day, but he did just as well as anyone else could have done since he had his limit along with the rest of us within minutes. Basically, he would cast the 'Spook' (Mirror Lure makes something called a 'top dawg' that is great for this too), and take all the slack out of his line, then reel it back in, jerking the rod tip up and down, slightly left/right, causing the lure to zig-zag as it was retrieved.
That's how I learned to walk the dog and why it would be a blast to try it.
Hope this helps,
Doad.
