I have 2.
The first one was July 20 1987 when I went solo for the first time. Nuff said there!
The second one was last Fri. It was my last flight for the company (changing jobs). A short run up the QLD coast to Cooktown, wx was stunning, view sensational.
It was my leg back, Cairns on dusk. We got vectored around some traffic that would have otherwise held us up by 10 min or so. Greaser of a landing

The only sour note, I was 2 hours late to my own farewell!
