Good for him, better for you! Keep him hooked.
AGFC has some good lake maps, Conway's map is really good. Most of those ramps would be fine to slide a boat off of.
Palarm and Caney are easy to get to and you can catch crappie there now. Gold Creek is possibly busier than you may be comfortable with. I like Adam's Lake and Green's Lake on the east, inside the management area. And a trolling motor is all you need there.
