LeadSled - interesting. I was aware of some of the controversy about the sale of the airport (complaints that the buyer wasn't taking care of it or the people using it) but I didn't realise that there had been questions about whether it was actually legitimate. I'll do more research on that.
Creampuff - at the moment it looks like the skydiving is doing very well (in that they're almost always using the Bandeirante rather than the C182s). Not much chance of that suddenly failing, unless a lot more competition appears.
