Very pretty young lady. Love her dress. That is quite a decision she has made. Don't know the requirements (I should) but can she apply to the Air Force Academy in Colorado Springs? Is she interested in continuing her education? My daughter went into the AF shortly after graduation and she is so glad that she did. She went in enlisted and then later went to Officer's school. She got to travel, got an education (now starting her PhD). She didn't initialy plan it, but it's become her career. 20 years now. She's only 39 so she'll probably put in 10 more and retire at age 50. Because of her moving around I've found new places to travel to. I've been to Japan, England, Wales, France. It's great to have a place to stay and she loves to have family visit.
Good luck to your granddaughter. (Lip ring has to go)
What base is she going to visit?
