I have a concern about the high cost of postage, to send them to be used. What do you all do about that? any suggestions for us? I would love to do it....my son JON is a Marine Corp Captain, helicoptor pilot and I sure have the gray hair to prove it....we / HE did Iraq and it was a scared time for us, as parents. My hubby was a Navy Lt. and flew F4J's....we did VN twice.......that was a worrisome time too.
