Fun, business, fun, private, fun, more fun
I'm seeing that the reasons we fly are:-
1) pure fun, eg just enjoying the scenery/sunset etc and nothing else.
2) technical fun, eg flight planning, operation of the aircraft, using all that training.
3) business, eg meetings. Sometimes you get there quicker by plane, sometimes not, but the business side of things helps justify having fun on the way.
4) Private, eg visiting friends, relatives, taking the wife and family out for the day/week etc. and having fun on the way.
I am beginning to see the common thread running through this list.... fun
