Any interest in another boy who won't even need a home provided for at least 8 more mos and will only have 18 mos after that before reaching 18yo? No long processes needed, physically healthy and can lift over 20 lbs, no learning curve necessary for you- he sounds very similar to what you're already used to and knows how to find his way back home if truant or out in the middle of the night- he always came back home!
