I recall reading that as well Bunch. A book I recall reading even states you couldn't land untill you did pull contrails. This was down the road from where I live. It was called Zellwood Air Station,now its called Bob White Field.... The airport is still in service, its a single strip that run north to south. They run small private aircraft some smaller twins. Its a shame they just tore a whole mess of it down for renovation. It got beat up due to the hurricanes we had..
