|We bought an audio tour app for Kathy's IPhone and proceeded on . It presents narrative on battle history according to our location, specific to the location. Ain't GPS great? My two impressions so far are: 1- how expansive an area the three day battle encompassed. 2 - all the stone monuments/plaques and cannons spread around the park. And the tremendous amount of information contained on those, like number of cannon balls shot by each battery on each day, let alone records of dead/wounded/missing for each regiment. We only got through two thirds of the tour on Tuesday. Today we should finish it and get into museums. It has been hot in the latter part of the day but cool at night.
