Yup, I have many times.
You HAVE to know the area though, or the surprise could be very dangerous and expensive. The safety of those "innocent" citizens on the ground is very much your responsibility. Let alone the risk of actually hitting someone, the simpl risk of them having an accident 'cause they were watching you do something unusual, is still your moral responsibility.
The authories may take an interest, so plan how you'll deal with that. If that aircraft is not one you own, also think about what you'll tell the owner! If you miss (or indeed - hit) something, and do damage, your insurance company might find a awy out of paying a claim. If you're breaking an air regulation (or other reg) by landing, the clause which probably says if you're breaking an air reg, you're no longer insured, will probably come into effect. Can you afford the damage yourself?
