may want to check with the people at the mall, local cops, etc to see if you'll be able to do this at the mall. I'm assuming you may get away with it for a while, but will be stopped eventaully. Maybe see who locally you can get a hold of for advise on how those things work and where you could set it up. Would hate to see you put a lot if time and effort into it just have the cops or mall security shoo you away shortly after setting up.
