I tend to be "cyclical" in my interests but flying has always been in there since first soloing in 1975... must have "given up" (left it all alone) 4 or 5 times.
I think I'm about to "give up" again soon unless I can actually find something to fly... I'm currently thinking of buying a sailing boat as it'll be more aaccessible.
Economics have never really been the problem (within the usual hobby budget), just my enthusiasm and the availability of suitable aeroplanes... both seem rather thin on the ground at the moment but maybe in a couple of years time I'll be selling the boat....
