Further progress
here. Added art and camps with little labels. Zoom in to see them. Also, if you can open the javascript console in your browser (often ctrl-or-option-shift-J), you'll see the data for each marker. It's obviously still a work in progress, but it's coming along. While the map is for 2017, the events and camp locations are from 2016. BMorg will release location data for the current year in about a week.
