Where have we been....

It was been almost a year since we published an ArresterNews, and as of late we have received a number of emails and calls wondering if all was well.  We appreciate the concern and are happy to say that everything is going very well, so well in fact, that we now find ourselves having to redefine our priorities in order to meet the increase in demand for our expertise.


We have not given up on our ArresterNews or publishing new ArresterFacts, and plan to continue our efforts to provide free resource papers and industry news whenever possible.  Thanks to those who have expressed the fact that they miss our publication and hope everyone finds our latest ArresterFacts on separation distance informative.
