When we link your new troop site to an existing troop site, we will copy all event locations from that troop into your site.
If you go to Calendar → Maintain Event Locations you will see all of these locations, as shown below.
Locations are "tightly linked" between the troop sites. If you update any information about a location on your site,
those changes will be immediately copied to the other troop's site. If you add a new location to your site, that location
will be immediately copied to the other troop's site.
The only exception is the location photo. Photos will not be synchronized.
