My Carbon Footprint

Well, my carbon foot print took a hit today, I flew to Baltimore on business. Both flights were at least pretty close to full.
I've done a half-ass effort at determining my carbon footprint before and it wasn't very good. Now with this, and flying again in June for Bitbee's college registration and again in September to get her to college. Ouch!
Guess I need to do a much better effort at all the other parts of my life to make up for it.
