This time, paper rejection

I received this in my mail (postal mail, not email) a few days ago from the American Water Works Association (AWWA):

Dear Mr. Vedachalam:

Thank you for submitting your abstract entitled (sic) "Designing an Automated Delivery Device for Chlorine Dioxide Disinfection" to the International Symposium on Waterborne Pathogens Planning Committee for consideration for a presentation at the 2010 symposium.

On behalf of the technical committee, I'm sorry to inform you that your abstract was not chosen for a technical session. The planning committee reviews all the submitted abstracts, taking into consideration the timeliness of the abstract topic, the number of abstracts submitted on a specific topic, and the limitation on the number of sessions.
...

And the letter talks about how my abstract was good, but didn't have a place in the program, yada, yada. I am sad, not for getting this paper rejected, but because I missed a chance to visit Manhattan Beach, California, the venue of the symposium. If you didn't know, the median price of a single family dwelling with an ocean view is close to 2.1 million dollars in that town. Wow!
