Bob:

Thanks for the excellent advice. That resolved the issue.  

I was mistakenly thinking that the RewriteCond did all of the matching.
I forgot about matching within the RewriteRule itself.

Thanks again!

Ken Morley

Your RegEx ^/(.*) is open for every request. To catch the "root"
request only, change it to ^/$ instead. Your condition checks the host
header. You're redirecting to the same host (www.saddlebrook.com), why
should the host header be different? It should match against your
RegEx if the host www.saddlebrook.com was requested, of course.
