Value betting in Giant pot--5/10 live

[dedenburn]

Live 5/10 game, 10 handed. This was my first hand at the table. I came in in the CO and posted blind.

Hero is CO with 7 [img]/images/graemlins/spade.gif[/img],7 [img]/images/graemlins/heart.gif[/img]
UTG folds, next five limp, Hero raises. Button cold calls both blinds and limpers call (18SB)

Flop: Q [img]/images/graemlins/club.gif[/img],7 [img]/images/graemlins/diamond.gif[/img], 6 [img]/images/graemlins/spade.gif[/img]
3 checks, UTG+2 bets, MP1 calls, MP2 calls, MP3 folds Hero raises, button calls, SB folds, BB calls, UTG+1 re-raises, UTG+2 calls, all MP's call, hero caps, everyone calls (23 BB)

Turn: 3 [img]/images/graemlins/club.gif[/img]
UTG+1 bets, 3 call, hero raises, button calls, BB folds, everyone else calls. (35 BB)

River: 2 [img]/images/graemlins/club.gif[/img]
Everyone checks to hero. Hero....???

I have two trains of thought here
-bet, because just about anything will call in this huge pot.
-check, because there are five hands out there and turn/river is just plain ugly.

What do yall think?
