From the International Society for Landscape, Place, & Material Culture:
The 2020 Annual Meeting, originally scheduled to take place in Atlantic City, New Jersey, this fall, has been canceled due to the Corona-virus pandemic. We will meet in Atlantic City in 2022. And we will very much look forward to seeing you next year in Tulsa, Oklahoma.
