When I first spotted this sign near the Command Tower, I swung around to see if a Bengal tiger had been automatically released behind me. No tiger, but I did find a few more of these signs along the walls as I continued my journey. When I regrouped with my tourmates, I asked our guide about these RUN FOR YOUR LIFE signs: He told me that when he was stationed at Fort Monroe, most of the training he did involved running along the fort's walls. These signs marked off quarter mile increments for such training.
