A LARC scavenger hunt
The next LARC assignment should really be in scavenger hunt form. Each team would be given a different first clue, that is "find and cite where in ____ resource you would go to learn about _____." Then, either looking in that book or after properly decoding the citation (which could be written to only be done with the correct use of the Blue Book), the next clue would reveal itself. There could even be dead ends if you did the citation wrong (i.e. 3rd series instead of 2nd). Since each team would have a different starting place and different subsequent clues (all of comparable difficulty, mind you), there would be no need to sabotage or hide books. Ooooh, what fun.
Damn, that was sad.
