Fold to the reraise preflop.

On the flop, his check is suspicious and all you have is a draw. This would smell like a check-raise (could he have reraised preflop with 66?)I'd be more worried about 99 or TT. I don't see a great course of action other than checking behind or pushing all-in, and I'd lean towards checking with the intent of releasing the hand unless you hit your draw.

Once you hit the river, you have to call his bet. You're a 2-1 dog to hit your draw, but the pot's giving you 3.7-1. You're committed.

I guess the moral of the story is not to call a preflop reraise with a marginal hand. Tom McEvoy writes that too many players overvalue a suited A, and I'd wager you wouldn't have called that reraise (or maybe even open-raised)with A7o. The fact that the 2 cards are suited only adds about 7% equity to the hand, plus a reraise from the SB means a very strong hand. Well, I'm sure you get the point. No use beating a dead horse.
