Summer Thunder is one of a kind.

Gregory Coco's A Concise Guide to the Artillery at Gettysburg is among the best short consideration of the topic. Spruill's is quite similar regarding the various artillery pieces and ammunition used by both armies. What makes Summer Thunder distinctive is the constant attention Spruill to the distance in yards between the tour stop and the distant targets and the ability of some pieces to reach further than others.

Several but not all the maps have topographic lines. Thankfully, the farm buildings, those still standing and those lost to time, are on the maps. Small disappointments in Summer Thunder include the omission of the Pennsylvania Reserves assault and capture of Houck's Ridge and the clearing of the Wheatfield after the Grand Assault. Also, the cavalry battles of July 3 are not covered. The July 2 artillery duel between the Federals East Cemetery Hill, McKnight's Knoll and Culp's Hill and the Confederates on Benner's Hill is addressed in an appendix.
