Chris:
I have what we call Chip-a-Tooth water out of our own well... I have found that when I am traveling, I can make lather by just looking at the brush and the soap it is so easy comparatively speaking... I compensate at home two ways, one I use Uberlather, it does work.. Two, really, really hot water helps a ton, however if you use boiling water that for some reason hinders the lather (I don't know why) Using these two things I get great lather even at home...
