Hey Phil!  I got your message about the theme I'm using and I think your Pirate idea is awesome!  I'm going with a Tropical Theme - the plane will be bright yellow (dark gray interior) and I'll be using vinyl graphics so that if I end up selling one day I can revert back to standard stripes etc.  I'm branding mine "Captain Crabby's Manatee Tours" in a large vinyl graphic and will have a mermaid for nose art.  I've also been thinking about having a pretend treasure map on the rear cabin wall to fill up that huge space and make the plane even more fun for the kids.  I'll add in other touches too.  YE is huge for us and I'm really looking forward to next spring - by the time I get my 40 hours flown off it will be winter :(
