First Support Base Washington 3 was built on sandy soil and dried quickly after rain. FSB Crook (Google FSB Crook RVN), a few miles west, was constructed in dirt so rains created a mud field that added extra effort to each job. The monsoon (wet) season was cooler but humid while the dry season was hotter dryer and the air was fouled with dust. Shooting a 105mm howitzer in mud was miserable; often rain would add to the fun. Any job on a gun crew was hard work but mud and rain were added insults! In the dry season, dust penetrated everything which required never ending cleaning.
