 ### Other Web Map Tools
 
-Leaflet is not the only tool available to create web maps. There are many tools and services that you can use to make webs maps, each with their own advantages, required skill sets, and price points. If you'd like to explore other options, you might consider Carto, Mapbox, ArcGIS Online, Story Maps (of the Knight Labs [open source] or ESRI [proprietary] flavors), Mango Map, GIS Cloud, Google Maps, D3, Here Maps, or OpenLayers.

-## Workshop Data: UC Davis Campus Cats
-In today's workshop, we'll be working with the UC Davis Campus Cats data set that was originally compiled by Rachel Bingham and Rachel Hale at the UC Davis Office of Educational Opportunity & Enrichment Services to facilitate the ["Campus Cat Safari" Connection](https://opportunity.ucdavis.edu/programs/aggie-connect/connections/campus-cat-safari-exploring-ucd-cats-campus) through the First Year Aggie Connection program.  This data was downloaded from [Rachel & Rachel's Google Map](https://www.google.com/maps/d/u/0/viewer?mid=1xN5Nv6t2rfAef66_vObEX3HbxkAalvlx&ll=38.53781472959825%2C-121.76011159999999&z=15) on 2021-10-14 and this data is used with permission from the authors. For this workshop, DataLab staff have processed the data from its original KML format to create a .geojson file embedded in a javascript file (more details on this process and why we did it to come).
+## Workshop Data: UC Davis Campus Food
+In today's workshop, we'll be working with the UC Davis Campus Food data set that was created by Naomi Kalman for this workshop. It shows places to get grab-and-go food on campus, in case you need to pick up a meal that is already prepared. Note: Naomi did this frequently and favors a tuna sandwich from the Silo Market. The data for this workshop is a subset of [Naomi's Google Map](https://www.google.com/maps/d/u/0/edit?mid=1emi8rdi4ixDfOcZtBvZzS0HcXTg_Hmc&usp=sharing), downloaded on 2023-04-04 and used with permission from the author.
