NPH at night

[Needlefish]

Took my younger son and we kayaked upper NPH late Saturday night on a fair high tide. Fished from 7PM to 10PM, but only got one sand bass and one HUGH butterfly ray by the PCH bridge. I didn't know that Plastic Navy had its tournament earlier that day........couldn't make it anyway, but would have been nice to see old friends. If anyone has some tips on fishing the bay at night, please advise.

Appreciate it.........
