spunrdneck - thank you for your helpful response, as well as all the other members that posted their advice (regardless how condescending, rude, helpful, or any combination of the above...)
Just so you all know, I consider myself a responsible individual... which was why I chose to fly my quad above condemned land across the street from my company - at any time during my flight if the quad were to fall from the sky, there would be 0% chance of it hitting any human or property. If I wanted to be a menace, endanger others, etc. I would be flying my quad in populated areas, with a laser or two strapped to it to incite panic. As it turned out, as soon as I noticed the stir it was causing last night, I loaded it into my car and went home.
With that said, I don't appreciate some of the rudeness displayed by some of you. I am reasonable, and if I did something wrong I'd be the first one to call myself on it, but I can't see what I could have done different. I had a question, and instead of shrugging and continuing flying at night in the same area I took it to the 'pros' here on the forum.
To all of those individuals, the "you're going to ruin it for the rest of us", just two words: grow. up.
This may come as a shock to you, but your hobby is the same hobby shared with many 8 year old kids - flying remote controlled aircraft - and not even high end custom built aircraft, but bought-off-the-shelf products, at a very reasonable cost. If you don't want kids ruining it for you, then here's a suggestion:
don't pick the same hobby as most kids. Again, this has been a public service announcement for all of you that need to wake up and realize what the average age group of participants in this hobby is.
With that said, I thank all of you that gave me useful advice once again. It's much appreciated
