I drive long distances quite often, and always have, but I too am having difficulty with them. I get very sleepy and can only really do at most 5 hours at a stretch. I break up an 800 mile trip from my home to that of one of my daughters into three days. Four hours the first day, 5 hours the second, and 2 1/2 the third day. I stay at the same airbnbs each trip. I am always very happy to arrive! I have learned one very important lesson on these trips: if possible, drive on major holidays! You have the roads nearly to yourself. If that's not possible, then Sundays are by far the best days on long distance drives, because far fewer large trucks are on the roads.
Love your photos! I want the blue house! I'm glad you could make the trip to see your brother. I'm sure he was glad to see you too.
