I think I have them all now... Finally finally got #4!
And I have PM's out to 12, 13 & 15 and I hope I've got them all right! But I have to darn near slap myself in the forhead for not getting one sooner as I read the second clue and it hit me like 30 minutes later DUH! I'm such a dork!
I think some of what people are having problems with is over thinking some of it! Good luck everyone!
