They performed military drills, gave a band concert, & manned displays of Civil War artifacts, which they explained with great familiarity. One friendly fellow used models of a human head & skull to show me how 19th century surgeons would carry out a trepanation & use a flattened silver coin to plug the hole.
The reenactors looked remarkably comfortable in their 19th century garb, & the setting couldn't be more authentic.
Fort Point must form some kind of natural wind tunnel. It was blustery & numbingly cold.
The chilling conditions didn't seem to bother the reenactors, who appeared entirely at home.
