Personally, and by personally I speak on the behalf of team 1024, we had a huge issue the past couple years with several (maybe about 6~8) people who magically showed up on the day we were going to leave to go out of town, and were registered for the team, but never showed up on any or many of the work days. Obviously they just wanted to cut class.
So, after rummaging around in the attic of McKenzie career center, we found a timecard puncher and a huuuuuge stack of timecards. Now we have a forty hour requirement that is surveyed by your subteam leader (programming, electrical, etc.). Basically, if you don't have forty documented hours, you don't travel.
Of course my programming kids won't have any problem with that... considering they've already met the 40 hour requirement and the season HASN'T EVEN STARTED...
Does that make me mean?
Quick swerve off topic: The programming project I dreamed up for us to work on 'does the wave' with a row of 8 airplane servos... turned out rockin sweet. I'll have to post video of it sometime... makes what looks just like ocean waves with a row of notecards... unfortunately, I opened a whole can of worms diving into some trig stuff: Now they want to build a small pen plotter! Oh if only we had more time before the season started...
