I know the Forum well...I was a legislative lobby chair for the HEC committee on a 2002 state education bill...we had a panel of national figures (HSLDA & NHERI etc) and state home education leaders present our side to the education sub committee there and the place was packed with homeschoolers. The architecture is wonderful and the kids relished the experience!
I was very impressed by the structure---seeing it empty- with that mournful organ music- was the surreal part.
