Tammy is actually available to game today, as she's on-call every alternating week. However, I am still pretty sick, and to be honest, the more talking I do, the more I cough. So gaming today is contra-indicated.
As a result, today's game session of the John Carter of Mars Roleplaying Game Sunday campaign is off.
This means another Sunday off, so will take the day to just relax, lie back, and try to heal. That, drink plenty of fluids, and stay warm.
