Yeah I bet that felt AMAZING to finish. Those pits get so nasty with old grease and random junk. Probably found some wild stuff down there. Huge respect for sticking with it for months.
Read a story once about a crew finding a full set of antique silverware and a motorcycle helmet in a pit like that. Paul_stone29 is right, the relief must be huge after dealing with that for months. The smell alone would be something else, like old oil and wet dirt mixed together. You'd need a serious pressure washer to even make a dent in that mess. What was the weirdest thing you actually pulled out of there?
Damn, that sounds like a brutal job. Can only imagine the kind of crap that builds up down there over the years. Serious relief to finally have it behind you, well done.
