if I am flying at say, an ice skating rink for example (not with tons of people on it), and they came out and told me I couldn't fly there. would I be able to continue flying legally? or would I have to keep a certain altitude? I probably wouldn't be a pain and land it but I just wonder if they called the police, if I could tell them that it is legal and that they couldn't hit me with a fine or arrest me.?
