The heart of the site - a granite wall that bears the name of the 646 local soldiers who died in the war - is now fully visible from the street.
A "got concrete?" sign sits among heaps of overturned dirt, exposed rebar and construction equipment. The remodeling project calls for 130 yards of concrete to be poured along Spruce Street, and supporters have been asking for donations.
Terry Williamson, the president of the memorial fund board, said the board is about $126,000 shy of the remodeling project's $500,000 price tag.
Miller, a La Salle College High School teacher who also sits on the board, set up a website where folks can donate to the project: www.gofundme.com/7rgclg.
"I started it about a week ago, with really no way of getting the word out, and we've already raised $645," he said.
Still, the board hopes that the majority of the overhaul, which includes repositioning eight 5-foot-wide granite panels that feature scenes from the war, will be completed by Memorial Day.
"Our object is to get people to see the memorial, to see the 646 names," Williamson said.
The redesign is also aimed at warding off vandals who previously took advantage of the memorial's enclosed design, Williamson said.
Miller, 65, sends his students to the memorial every year. He has them copy down the name of a fallen local soldier - and then repeat the task among the sea of 58,000 names that are engraved on the national Vietnam Veterans Memorial in Washington, D.C.
"I teach them to appreciate how lucky they are to be in a time where they have choices. We were drafted," said Miller, who served a year in Da Nang.
"The goal is also to learn from history, to not repeat stupid mistakes," he said.
"I want my students to look at the bigger picture of what it means to go to war. It's not some fun thing."
