[Riverman]

Thanks for the responses.

I raised the river and got 3-bet by the original bettor. I made the crying call and lost to A 3o

I think my mistake in the hand is not checkraising the flop. As others have pointed out, the many scary turn cards mean that it is just not likely enough that I will have the opportunity to check-raise on the turn. (As indicated by my having to bet the turn)

I think not betting the turn is horrible poker, and that against this passive crowd the river raise is -EV.

Thanks to all.
