Don,
Are you aware that you can claim PDUs for working as a professional in project management? I encourage you to read the PMP Handbook section on PDUs -- under Category F, you are currently able to claim 5 PDUs per every 12 months of work as a project manager, for a maximum of 15 per recertification cycle.
Please note that the PDU requirements are changing this fall. If your cerification is due this July, you'll be using the current rules. However, next time you'll need to follow the new requirements. Please reference
PMI's site explaining the changes.
