I work at a company that every once in a while a big hands on, "every body pitch in" to do assembly line work for shipping, or building something for a con. So exhausting, but some of the most fun times too; to see the normally standoffish front office employees and upper managers getting lapped in the folding and envelope stuffing. Those diversions from normal work are one of the things I look forward too.
Good times good times. Looks like you all earned some happy memories there. Hope the convention gives you just a enough challenge to make you feel you earned it, and smoothly enough that you know you did a good job planning and executing.
