Why do teams voluntarily do FIRST without adult technical mentors?

[Cuog]

In My Opinion a team should be run by the students. The students should begin the design and the Mentors job should be to keep the students on the right path and provide ideas/suggestions when the students dont know what they should do. I as a student dont like to see a team that has had no help from there mentors or has no mentors to ask for help. What also bothers me is when it is the mentors that do everything and the students only know from what the mentors have told them about the robot.

Our team is a small one(20 something students getting near 30 now) with only 2 real mentors, as well as some parents that help out when we need them. I like our team the way that it is larger teams cause each student to have less and less to do, as it is during build season we always have at least 2 people sitting and doing nothing at any particular point in time.

Well I've said my piece but feel free to think what you want,
