I couldn't agree more on the fun thing. While most probably wouldn't look at Pika as being a "fun" buggy program, I can tell you that we had a great time working together. I was pleasantly surprised that some of the goofy, fun traditions still exist in the program and most of them are just stupid, yet relieve a lot of stress.
Also, mechanics who are team builders and leaders is what helped for my team. Our push team was gigantic, we had 6 teams. We had 3 Push team captains to move that along. We also had like 9 mechanics and almost any senior who was gung ho could help out. I guess I was lucky that I had a bunch of leaders who were all aligned to a common goal. That helps.
