Echoing some previous points:
- Beware lack of currency. If you haven't flown much for a few months, take a check-ride, then fly on your own until you're sure you on top form.
- Flying with a passenger can be distracting - again, ensure your currency before flying with passengers.
- Beware short winter days. Plan to be back home from any long trip at least 30 mins before sunset.
- Beware landing on runway headings between 220 and 260 within 30 mins of sunset (sun in your eyes).
