I guess I've been lucky!

I did run into a retro today that could have been a nightmare if I hadn't spent about an hour with a tape measure.

Finished top and bottom.

Right below the chosen location (had to go down) was a pex,vent,and sub panel run.

I was able to dodge everything by about 1/2" after careful planning.

If I would have just drilled down blindly,it wouldn't have been good!
