I was able speak with Bud this spring and he said his attorney has advised him not to give permission to land.
He did ask that if by chance I had some carb ice on my way by that I tell Butch (his nephew) hi.
I highly doubt you'll be able to spend a night, but if you have a gift to offer Butch he'll give you a heck of a tour. (my copy of Fly Utah! was exchanged for a very impressive tour)
I have heard that Bud's health is unstable and also that the runway has been closed some. I would proceed carefully, good luck.
