Most of the major questions about your network or system can be answered while at ICCM, and you will learn a lot about new technologies. The big thing, which you will not realize you are bringing back, are the friendships with others in your field. When you have a major techie catastrophe down the road, you will have a bunch of experienced techies you can contact to walk with you. Sometimes ICCM gives you the knowledge in advance, but often ICCM helps by giving you the contacts who can help.
