Latex Letter: From Address Left aligned

Question

This is my first time using Latex to write a letter. I am using the letter class. When I use:

\address{100 From Address \\ City, State \\ Pin}

The from address becomes right aligned. Is there someway I can make this left aligned. The format of the letter I am looking for is: the from address left aligned, followed by the date left aligned, followed by the to address left aligned, then opening and body, and finally signature left aligned.

I managed to get the signature left aligned by using: \longindentation=0pt, the rest of the items are properly aligned - its just the from address that is right aligned.

\makeatletter
\def\opening#1{\ifx\@empty\fromaddress
  \thispagestyle{firstpage}%
    {\raggedleft\@date\par}%
  \else  % home address
    \thispagestyle{empty}%
    {\noindent\let\\\cr\halign{##\hfil\cr\ignorespaces
      \fromaddress \cr\noalign{\kern 2\parskip}%
      \@date\cr}\par}%
  \fi
  \vspace{2\parskip}%
  {\raggedright \toname \\ \toaddress \par}%
  \vspace{2\parskip}%
  #1\par\nobreak}
