Thanks again g1!

For some reason your first conditional redirect causes an internal server error (RewriteCond: bad flag delimiters):

RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /California/index\.shtml[^ ]*\ HTTP/
RewriteRule ^California/index\.shtml http://www.example.com/California/ [R=301,L]

Sorry about my sloppy coding on $2, I've recycled this from another section which makes use of it.

As far as the trailing slashes, unfortunately it's a bit of a site-wide policy for consistency. This is not to say we can't drop the slash, but would like to do it all at once after enough time has passed with some other 301's which have been implemented.
