Bring your old conference bags and get new ones! We'll have a space set aside, so you can let go of all those bags that are cluttering up your office, home, and car. Then you can take others that will work better for you. 

Think of the interesting conversations you'll have with colleagues about those conferences that you've attended! You may learn about new and stimulating places to visit both professionally and personally and you'll save the environment while you're doing it.
