lots of "professionals" on the forum with varying degrees of experience and or making one's career or job from it out there. I suspect that's in part what your questionings' about.
Read thru the forum and you have many including me that are always available, otherwise if you see others, PM or E-Mail them when and or if they did not respond but you theorize that they might be of help and I'm sure they would be. Wolf for instance might not check in this week but he also makes his living doing this type of thing. E-Mail away or PM him and he would respond.
Yeah, I make my home in Aurora these days. Sorry, don't really work in any particular theaters. My work varies but I do alot of drafting these days. But you might see me in a convention center or your local concert venue.
