Hey Ted! I'm similary to your situation. Single, nevery married; adopted my 12 year old son in 2000 when he was just turning 7. Never a moment of regret. Hard to even remember when I was "single". Probably have all the similar challenges you have; support systems, chilld car for late nights and early mornings, deployment backup plans, etc. With all the challenges, I wouldn't change a thing. Actually, I'm working on adopting #2 ()nut's ain't I....?
Good to know that the single adoptive father club in the AF is club of at least 2. Take care!
