[Warren Boudreau]

Engineers, programmers, and such are all good to have as mentors on a team. But don't overlook the people who actually make the parts. This can be anyone who is handy with woodworking and/or metalworking.
And, most of all, don't forget the "team mom". Somebody has to make sure that everyone eats during the all-nighters just before shipping and that the team t-shirts get washed during the competitions and all of the other unappreciated tasks that need to get done but nobody thinks about doing. Team mom's are the best asset you can have.
