In 2281, while on layover in Boulder City awaiting a caravan to take him back to New California, Donald's younger brother, a private himself, spent the time in-between paying his respects at the Memorial.[3][4]
↑The Courier: "What is this memorial?" Kowalski: "It commemorates the Battle of Hoover Dam. The rangers lured the best of Caesar's Legion into Boulder City, then blew the whole town up. The NCR still lost a bunch of troops in the fighting, though. My older brother sacrificed himself so they could evacuate some of the wounded." (Kowalski's dialogue)
↑Kowalski: "What the fuck are you doing? My brother died at the Battle of Hoover Dam. You're desecrating a war memorial." (Kowalski's dialogue)
↑The Courier: "Where are you normally stationed?" Kowalski: "Camp McCarran, but I'm on leave at the moment - heading back to California to see my folks. I'm supposed to join up with a caravan that's heading that way up at the 188, but they're not due to arrive for awhile yet." (Kowalski's dialogue)
