You know that orange fence they use to demarcate ski area boundaries? How about that stuff? Note that it can get prohibitively expensive depending on how much of that fence you need but at least it's a semi permanent structure.
I'm not going to harp about safety or potential bystanders around since I assume you know what you're doing being an AV rep and all.
