77 Hand That's Bugging Me. Was I weak/tight or right?

[MrHorace]

Live 2/4 Game at Table that seems pretty solid. Maybe a bit loose, but not passive, and raising in proper situations.

Hero is MP2 w/ 77
1 fold, MP2 calls, about 3 others call. No raises.

Flop: 458, w/I recall being 2 [img]/images/graemlins/club.gif[/img]s.
May be wrong on this 2 clubs, but think I'm not.
Checked to me, I bet, a couple other callers. I don't recall any raising. So about 8-10 sb in pot.

Turn: K [img]/images/graemlins/club.gif[/img]
Checked to me, I check. Guy to my left bets, another bets. And to me.
I look at the pot, and estimate (yes, need to get better about counting bets WHILE the action is happening) about 6-8 bb in pot. My outs are the 2-7's and the gutshot 6's. But if I make my straight, I don't necessarily have the nuts.
So I fold.
Was I correct in doing so?
Thanks,
