Thank you, it looks like valuable commentary.

Thanks from this lazy boat owner. I've been meaning to track him down. I should have known that all I had to do is wait a little while and the list would take care of it for me.

I second that... here are a couple of pictures of the lettering Rik did
for me last year. The last e-mail I had for him was: rik at signsbyrik.net<mailto:rik at signsbyrik.net>.
