All
I reckon I have to put down in a field a couple of times each year due to deteriorating weather. I don't give it a seconds thought and so far I've never had an issue with a land owner because of it.
Recently on a trip to Paris (not that we got there) I ended up parking my JetBox in a sewage farm and taking refuge in someones house for a few hours until I was able to re-trace my steps home.!
I have found that some recently qualified pilots are far too concerned about landing on private property than they are about making a precautionary landing. It's simply a no-brainer - if you're not happy, put the thing down. 99% of the time, most landowners either won't ever know or equally won't care (as long as you've not damaged anything).
I wrote about our failed Paris trip on my blog
here if you're interested.
