There is definitely somehting about the Cessna 180/185 - I've always seen them as a classic from about the age of six (my very limited experince is all 152/172) but... the 190? A real classic, but not quite such a bush plane perhaps?
Did you see a programme on the telly a couple of years ago which featured Docu-hero hitching a lift with Alan Root (Mr African Wildlife cinematographer and balloonist) in a 180... blew the rear tyre and bungied a spade to the tail wheel leg to act as rudamentry skid... great stuff!
Then again the Cub is a super aeroplane as well, as are those in Mark's list...
