I am interested in the Open Glider Network (OGN) work with a possible implementation around the Chicago area.

Looks like you found a project with a good fun to effort ratio.


The US coverage map is slim:

But a tracking station looks easy:

To get coverage for a task area, you might want either a mountain top or a handful of sites?
