Word-wrap/hyphenation with very large font size not working consistently

I am trying to typeset some signs for a construction site.  I enclose a 
(somewhat contrived) for consideration.

What I am having difficulty with is to get word wrap and interline spacing to 
work consistently.  I am using \framed, but if there is a better way please let 
me know.  The trouble I am having is getting lines to break consistently. 
Sometimes they do, but as in this case the second word `through' continues 
beyond the frame width.  You may also try to substitute the text ``Enter this 
way today'', another contrived example to see the effect.  The symbol font that 
I am using is Symbol-Signs from:

http://www.fontsquirrel.com/fonts/Symbol-Signs

but I shouldn't think that is pertinent to the problem.

Any guidance on what is the issue here?  Or if there is a better way to go about 
doing this type of signage.

I am also interested in learning how to do vertical centering of blocks of text, 
i.e., in a formal letter or in this case of setting text for signs.  I have read 
and tried to understand Wolfgang's response to Jaroslav's earlier enquiry:

http://archive.contextgarden.net/message/20100702.112805.07aa71e2.en.html

but I really don't understand it and how to make it work for my applications. 
Is there a simple template---say for a block of text---that someone might be 
able to offer for the ConTeXt challenged?

advTHANKSance
