I put an article in the Fishing article Forum back on April 25, 2010 titled “Cat Tip of the Day: Drifting for Channel Cats”. I think this is exactly what you are looking for and should help you put a few channel cats in the boat. I normally drift south of Stillwater near the new bridge down around the King Plant in Bayport. Good area for drifting.
I was going to give you a link to the article but cannot seem to enter a link for some reason. Do it this way. Go to Fishing Forums then go to Fishing Articles then go to Page 3 on that forum and there you should see the article – Cat Tip of the Day: Drifting for Channel Cats.
