my son challenged me. It took my lifetime to finally do it (70+), but now, my son (who was with me for #50) has challenged me to do it again - in one year. So - looking at routes and may split it into 2 trips (in my M3). Will also require a third trip (Alaska/Hawaii) via air. In late April... Starting from here (Central Cost Calif) But will fly home at one point for a break - then back - to continue. Alaska/Hawaii can be anytime (even winter) cuz basically I can just fly to Anchorage - change planes to Hawaii. Just looking for input.
