May is "Preservation Month," an initiative of the National Trust for Historic Preservation to raise awareness of the necessity to care for and support our historic structures. The Trust encourages everyone to plan special events and tours that engage the public in the cause of preservation. This year's theme is "See! Save! Celebrate!" and the hash tag for related tweets is #presmonth. See the Trust's Preservation Month website for ideas of things you can do to get the word out.
