To have your own flying field is not only the land you need, it is also the paved runway. It is expensive.......$85-90,000.00
Also I will miss the chatting with all my flying buddies, the laughter with the kangaroos, the planning of the events, the swaping of equipment.
I think a lot of the addiction has to do with the support groups ( the flying club), the sponsor (your flying instructor), and the frequent meetings (your trips to the field)
