Options after turning 18

[SWdenleader]

 We have a scout turning 18 at the very beginning of the senior year. On that date, membership in the troop is complete (I believe). However, the youth is still interested in participating in Scouting, to include OA activities for that last year. I'm looking at options; I've heard Sea Scouts and Venture Scouts go past 18, though I'm not aware of any groups in the area. I suppose I could look it up. Would rejoining the troop as an adult member be an option? What other possibilities are out there?

 Wondering if anyone has experience in this and what path they took.
