Fort Moultrie's front gate. As soon as you enter, the Post Commander, represented by a brown metal sign, informs you that you will: Stay off the walls and mounds. Keep pets outside the fort. Deposit litter in trash barrels. I complied with the Post Commander on his second and third commandments, but took the first as more of a suggestion...although the climbing that I did do was with the utmost of care and consideration for the fort's hundreds of years of service to our nation.
