Before every backpack trip, we hold a trip planning meeting. We call it a “trip planning” meeting; in truth, the trips are pretty much already planned. It’s more of a “trip explanation” meeting. We go over basic logistics: carpooling, the route, the campsites, where we’ll find water, the weather forecast, any special precautions to take — for instance, if it’s an exposed route, bring extra sunscreen; if there are multiple water crossings, bring water shoes; if there are bears, bring a bear canister.
