Does your team charge a fee to join?

[FrankJ]

Not really suggesting anything about dues or joining fees. But FRC is an expensive sport.
$5000 for your veteran robot to go to one regional (two district).
About $.50 to $1.00 a mile to transport your pit & robot to a competition.
$300 to $600 /person to transport, house & feed you team per event. Somewhat less if you don't have to use hotels. Somewhat more if you use airplanes.
This does not include build costs for the robot or tee shirts & uniforms, pay for the teachers, coaches, mentors. The costs get absorbed in various ways (including supportive parents carpooling), but they are real just the same.
