Not DrupalCon or DrupalCron, but DrupalCorn. I am co-chairing the committee organizing the conference and will be doing a session on search engine optimization in Drupal. The conference is August 3rd and 4th and only costs $20! It includes lunch both days and a social event the Friday night. For an extra $20 you can sign up for a full day of training before the camp. Definitely worth checking out if you are doing anything Drupal.
