One example would be the multi-layer perking structure underneath a full=
 size soccer field at UCLA.

A "multi-layer perking structure"? How much coffee does THAT make? ;-)

I highly doubt that there is any "image" projected onto the lens. You can
prove this for yourself by putting a transparent piece of paper (with an
arrow or other symbol drawn on it) in the gobo slot. Remove the lamp and
reflector, use a 3.5Q if you have one - as it makes the task trivial.
Place a regular light bulb inside the instrument and block stray light.
Project the dim image in a dark room and observe the effect. Try a shutter
and see what happens.

Dim red light does not destroy dark adaptation. However, if they were
bright enough and aimed at the audience, they would act as blinders.
Unfortunately, it would also reduce the perceived brightness of the UV
effect.

Cirque is currenlty playing Bridgeport, CT.  However, it is there
first ever arenas tour...  I am in CT but haven't seen many tent shows
here, aside from small local stuff.  Never dealt with the permitting.

Try getting in touch with Stamford Tent http://www.stamfordtent.com/
