Dave, since you're "in the industry" and probably have a lot of contacts, do you reckon you'd be able to get us a tour of something like a Bureau of Meteorology radar site or maybe take a trip up to Parkes and get a behind-the-scenes tour of the Parkes Radio Telescope?
I'm sure I speak on behalf of many of your viewers when I say we loved your tour of the old Channel Seven analog television transmission facility at Artarmon (for those who haven't seen it, it's linked down below). It's certainly one of my favourite episodes to-date.
P.S.: Also check your P.M's for a message from me. Might be worth exploring.
