Stop by Thumpers up by Lake LAVON and talk to Tommy Ezell. He knows Hubbard pretty well.
If you live by Hubbard I would recommend just driving over to Lake Fork or Lake Tawokini.
The quality of the Crappie on those lakes makes the drive worth it.
Or go to Lake Lavon another excellent Crappie Lake.
LAVON you can fish Timber or brush piles. You can fish the rocks down by the dam.
Tawokini and Fork all the bridges are holding fish as well as Timber.
