@WD: I know it's not my turn for a while yet, but I was just curious - have the drudges moved this round? If they haven't, then right about now would be a really good time to use the log trap, right?
Also, what kind of action would it be to trip the log traps? I quickly skimmed the old posts, but couldn't find one where you stated what kind of action it would be. If it's only a minor action I could run up and trigger one of them this round, otherwise I'd need to burn an action point to do it this round.
