Thanks for the feedback Machka. I wish I had time to do one of these. Unfortunately, due to the awesomeness of the school scheduling, I get to turn in my paper at the end of the semester (December). But the entire thing (doing some online research) has sparked my interest in going (maybe next summer). I didn't realize that there were so many people who didn't use a company- I guess I need to work on my Google skills. Thanks again.
