This is a general checklist for myself and anybody else planning to do long road/climbing trips such as California Death Valley Road Trip. It is meant to be useful both before and after the trip. Before the trip, it is useful to investigate possible campgrounds, and nearby peaks that may be of interest.
It covers how to set up the navigation Apps on your cell phone, how to perform key functions.
After the trip, it discusses how to prepare the waypoints using GMap "Draw and Save."
