Doug Seiler, Principal Architect for Seiler+Drury Architecture, who is in charge of the preservation work at Thunderbird Lodge, walked us through the different projects that have been completed or will finish up this summer in  a Zoom lecture on June 23.  Because the Centennial Foundation has been given a second $100,000 grant from the State of Pennsylvania, he also gave us a hint as to the next projects to be tackled.
