Tonight more under floor was revealed, much to our delight it was a bit easier coming up (east side):

Some of the plumbing rough-ins (blue tape covers the top of the drains, since they are connected to the sewer line but don’t have traps yet):

Of course the piece under the tub wasn’t attached so it came up very quickly:

Pex, insulation, sistered beams, plumbing supplies… It’s all here!
