Luton remain in the Blue Square Bet Premier play-off places despite a draw with Grimsby.
The hosts started well and Keith Keane saw his 30-yard strike well saved by keeper James McKeown, before Andre Gray headed over when well placed to score.
He made amends in the second half when he crashed in a volley from close range to give the Hatters the lead.
But the visitors were not to be denied and they levelled when Kiernan Hughes-Mason slotted in from 12 yards.
VIEWS FROM DRESSING ROOM
Luton manager Gray Brabin told BBC Three Counties Radio:
"I thought we dominated the game. I thought we definitely got a response. That was more like it.
"When we've gone that goal up, it was just rewards but at the moment we just don't seem to be getting that extra bit of luck that we need.
"Andre (Gray) was signed for exactly what he's done today. He'll work tirelessly, he's got a goal in him, he never gives up - and I thought he looked a threat all afternoon."
Grimsby Town joint-manager Rob Scott told BBC Radio Humberside:
"We came with a game-plan and started with a formation, which is a little bit different from normal, and we stuck our hands up after 15 minutes and said that it wasn't really working.
"We went to a more solid four-four-two and everybody knew their jobs.
"The attitude of the players was first class, they never know when they're beaten."
