Denver is going to be a busy place for map lovers this month. The International Map Collectors’ Society’s symposium takes place between September 18 and 23, and is held in conjunction with the Rocky Mountain Map Society’s antique map fair, which takes place just before the symposium on September 17 and 18. The symposium also overlaps with the GIS in the Rockies conference, which takes place September 21 to 23. No wonder that week has been proclaimed GIS Week by the Colorado governor.
