Piper you dont have that option on Port Property as told to us by Mike davidson . he said very clearly that i am not allowed to play on Port Proerty even if I am not busking.
In 2004 I did just that and was accosted by six Port Authority personel. They threatened me for playing PUFF THE MAGIC DRAGON to a group of little kids.
Be careful . They can charge you under the CAnada Marine Act as a public nuisance if they so choose. i still have the letter from Mike Davidson to Jeff Lott chief of police to prove it.
