18 y.o - work and she's planning days out with friends and her gf
17 y.o - work and again days out
15 y.o - wants to look into an apprenicship possibly but he's undecided so he might be at home all summer, which I wouldn't mind he's great with babies.
12 y.o - Around the house or off playing with friends for most of the summer. There's one, possibly two weeks of activites provided by a local school. But we don't know if he's got a place in the second week yet. And I swear I've heard the words tree house and fort so, possibly a project that'll keep them all entertained for a few days; hopefully weeks.
