I have early planning on a goal I set years ago; to fly my Mooney M20J from my home in eastern Maryland to the West Coast and back; out by Southern Route and back by Northern Route. I need stops in Grand Canyon, Los Angelas area, San Francisco area, and Casper Wyoming. I am seeking advice from those more experienced at these passages; I have been as far as Casper from here. I plan to do this in the mid Spring so density altitude is better but it's warmer than Winter. I am normally aspirated; no turbocharger, no deice capability.
