The highlight of the conference was the train ride from Altoona, at the base of the Allegheny Front, to Gallitzin, at the top of the Allegheny Front. The participants then walked backed to Altoona along the Pennsylvania Railroad tracks, past the Horseshoe Curve- a distance of about 10 miles, in temperatures over 90 degrees F!  The train ride was re-run in 2003, minus the walk back to Altoona.
