I've done it everywhere.

The skatepark.
In A public park on a bench out in the open.
Near a levie that has been turned into a half pipe.
In a cemetery (This can be very trippy. Especially at night.)
In front and inside school.
In front of my house
Walking down my street...
In front of my mall...
I blazed a J in a bar once lol.

And a ton of other places I can't think of...

But yeah... I'll blaze anywhere. Getting caught is the last thing on my mind. Hell, in Little Five points I was walking down the street with a J in my hand. As I was blowing out my hit I said hello to a cop. (But I did get the hell on...)
