Ok, everybody knows that heaven spots are perfect for proving your worth. But how far are you willing to go? Billboards are pretty good spots but have a high "getting caught" factor. Bridges and smokestacks, especially the big ones, are they worth it? Im asking the writers who have survived getting waaayy up, why, how, and where do you draw the line. Im asking all else, would you do it? and if you have a canvas in mind, Post it. Before and after.
