For the past couple years, the Tree of Knowledge has gone up in West Chester outside the Chester County Courthouse, thanks to the Freethought Society of Greater Philadelphia.
It’s a great monument to human thought:

This year, new size restrictions were put in place that could’ve prevented the Tree from being put up (PDF).
There’s good news today: The 10 foot high Tree of Knowledge was one of only three installations to be given a green light for this holiday season.
It will be going up this Monday evening at 5:00 p.m. and volunteers can help decorate the tree at 9:00 a.m. that same morning.
Congratulations to Margaret Downey and Sally Flynn for being such positive advocates for FSGP and the non-theistic community at large. This will be a beautiful display as it always is, I’m sure.
