What's the right play?

[DrWily]

Daytona 1-2NL
Standard issue Florida 1/2. Loose, lots of action.
utg limps, utg +1 limps
few middle positions limp.
I raise to 15 in the CO with AJsh
Folds to BB who calls. (solid player who's taken a few tough beats recently)
Two middle positions call.

Flop comes 3 7 9 w/2 hearts.

BB pushes in for 80 (60 in pot)
Folded to me.
BB forgets I'm in the hand and exposes the 9 of clubs.
