Help On The Road

[davidkerryedwards]

I think Evans was running about $25 per gallon last time I checked.
The system has to be completely purged of any H2O before adding Evans.

Another factor at these elevations is the reduced boiling temperature
due to the altitude. It's hard to get a good cup of tea around here
because the water doesn't get hot enough before boiling.
