A heads up:

A post on Language Log today 
(http://itre.cis.upenn.edu/~myl/languagelog/archives/003685.html) might 
be of interest to those of you who have some knowledge of highway 
signage fonts. In particular, if you are familiar with the new series 
that was released last year (or earlier this year???), you might have 
the answer to the question as posed, regarding a dotless lowercase i. Or 
if you know something in particular about Georgia signage, you might be 
able to help.
