Houston and Galveston
Hendrickson spent around 7 1/2 months in Houston training at Camp Logan. While at Camp Logan, Hendrickson had the opportunity to explore all that Houston and the surrounding communities had to offer. Houston, Hendrickson thought, was "some city" in which some locals still hadn't forgotten the Civil War: "it is noticeable by their actions, while they treat us alright, yet there is something lacking" (October 1, 1917).
While in Houston he also took numerous trips to the port town of Galveston, which at this time was still recovering from the devastating hurricane of 1900 that caused approximately 10,000 deaths, but Hendrickson still loved the city. In Galveston, he swam in salty ocean water for the first time, gleefully reporting it felt "swell to [lie] on the beach and let the waves wash up over you" (October 1, 1917).
In Houston, Hendrickson also joined the Masonic Brotherhood, at the Holland Lodge in Downtown Houston.
