I thought adding $args to the end of the try_files line would work but 
that appeared to mess it up more. Is there any way to get the try_files 
version to work like the old version?

Been staring at this but I don't see how
rewrite ^/galleries(/.*$|$) /galleries.php?mypath=$1 last; passes the 
path and additional GET variables, but the try_files version doesn't 
pass on the additional variables.
