The mixed crowd problem
A bar mitzvah usually puts three generations in one room, and that is exactly what breaks most activities. Missions that need running lose half the crowd, and missions that need knowledge lose the other half.
So the route leans on teamwork and photography. Both are playable at any age and any pace, and both push the teams to mix instead of splitting along age lines.
A finish that leads into the event
The route runs four stages with a real finale, because there is a ceremony to build toward. The last stage is the hardest and it ends at a point you choose, so the game finishes exactly where the event carries on.
Afterwards every team gets its photos and its ranking, and you get a full report of who answered what.
