I was driving through the area one day, and surprisingly saw that no one had listed this yet. There is parking along the side of the road. There are two granite memorials there. Please take the time to read both. There is one that lists the names from Bowie of those who served during armed conflict with two words at the top. That is the log password. While it is optional, you may also take a picture at the site to post with your log.
From the City of Bowie web site: Veterans Park - This memorial park contains open space and a memorial to those residents of Bowie who have served in the military during armed conflict and those who have given their lives in service to their country. It is the site of the annual Memorial Day and Veterans Day ceremonies.
