Sounds like a great trip Rich, got me feeling jealous!
Just to make you feel younger, I worked out some similar calculations to yours, and now I feel even older.
I have spent 75% of my life legally riding bikes,
(they only let me have a licence when I was 16),
so I wasted some of my time before that ........................................
but there were some adventures in the local fields on old 125 BSA Bantams and similar.
(The young ladies always complained that they were not very comfortable, but the grass was wet!)
I officially started riding bikes 47 years ago!
I'd go and get mi pipe and slippers if I could bloody rember where I'd put them.
P.S. just remembered I packed up smoking 5 or 6 years ago, so forget the pipe.
Then again I've done that already,
Dooooh.
Dementia don't you just love it.
Forget the bloody slippers, I know where my bike boots are........
and I know where the bikes are .....................
