Congrats, biking in your sixties is awesome! Just remember that 95% of your peers (just made up that stat) aren't doing what you are doing.

For a first tour just getting out and going is the goal. I find taking a camera and looking for unique shots, even of common stuff like road signs or barns makes the scenery that much more interesting. People can get carried away with always needing "dramatic" locales. If left unchecked it can lead to "been there - done that" syndrome that usually means getting out of bike touring after a year or two.
