I'm in the former camp, and for us obsessive logisticians, getting everything written and shared can be a challenge. Nailing down details like campsite reservations, meals, snacks, who's bringing different items, and what activities you can participate in can be a logistical nightmare. But I love camping, and I love sharing experiences with friends, so trip planning challenges will never keep me from wanting to spend time with people I care about outdoors.
Over the years, I've tried and seen a number of different solutions with respect to trip planning, including online checklist options like Packwhiz, extremely long email chains, and everything in between. My most recent go-to option? Google Drive, and more specifically, Google Sheets. My tripmates and I build a Google Sheet with multiple tabs representing topic areas like group gear, individual gear, the itinerary, addresses and phone numbers, and meal planning. Google makes it easy to share and edit the document, which is key.
