Yeah, pretty cool. I think not rigging in there when it's crowded (like a weekend) is probably wise.

But, there is no rule against it. I heard it from Jim personally and asked twice, to make sure.
Common sense and staying out if it's crowded is probably smart.
You could always rig just a tad N of the main area, that would work, I think.
I have done that with Chris Moore. I worked out fine.
