I will agree that is was a pretty good episode.
MP - neat how they finally found someone to see how far off straight the 4" holes are. Those last 2 were like 8' one way and 4' the other. That's a big discrepancy! Can make finding the actual MP and searcher tunnel 6 hard to fathom. What one did you find? Was looking for the MP vault but we found searcher 6 or vice versa. Neat still none the less. And it looks like they are bringing back the huge caissons again! What will they NOT find this time? Endless choices.
I did like that odd rock find, off in the woods, near the well, nobody ever saw this before? Like Caryl says above... I think he was watering the trees! LOL Don't think the lydar radar will show anything... just a rock that was split from another I will guess.
So the Lags have been there for what 10 years now and they still are going around looking for info? Did that lil archive place just opened last week? That info was never found before? Strange how it came to light in the same episode as needed? The "cool" article was from 1865 or so?
6' apart, 66' long, triangle drains with tons of coconut fiber covering them? They even change the pic from the square drains to triangle ones. I was gonna take a pic , should have. Fits in with what they are doing right now.... coincidence or great editing? Hmmmm

I do like all the action at Smiths cove but we still need who, why and when? Some pretty deep stuff being found. Will it get explained this season? I hope so.
I don't think I missed anything.... these were the big points in last nights episode.
