I wish I could help with more specific information: But I have seen where most night fishermen are setting up around the bridge just Northeast of Holleman's Boat Ramp.
I believe most are finding more on that end of the lake than at the Crosspointe end... but that may have changed since a couple of weeks ago.
Good luck to you and your son. I really hope you can find a couple of good messes and a good time of it.
