I co-owned a tanning salon back in the early 90's.One of the things my partner and I discovered pretty early,was that the air vent for the last tanning booth exited right into our office.And we got to see some great shows over the next few years.Never was able to get any video or pictures due to the lighting conditions.But Still have very fond memories of those days.If only we'd had the video gear they have now.All well.
