No place for water to get in, nothing to drain, nice smooth look. Just my $0.02.
Roger, thanks for the feed back. Reason for a drain, I just figured it's be a good thing to have in case water did get in there. You're probably right about it not needing one. I guess I'll have to pop the back glass out and look into this some more.
