That's the title of an article in the Gazette. Though they don't give good examples:
For the last three years, [Fred] Gasper has actively campaigned for more crosswalks and street signs to be installed at various intersections in the area, particularly in front of Eleanor Roosevelt High School in Greenbelt and in front of DuVal High School in Lanham.
Which aren't purely cycling related. But there is no doubting his dedication and it provides an interesting look into the kind of work even little changes require.
He has written letters to his council members, delegates and state senators lobbying for the features at the intersection. He has also made several PowerPoint presentations to area civic associations including the Glenn Dale Civic Association.
His top project:
What Gasper said he would most like to see is a contiguous trail connecting Good Luck and Greenbelt roads to accommodate cyclists.
Hmm, you can already do that by riding the road through Greenbelt National Park, a short but nice ride BTW, so I wonder if he means somewhere else or a more direct route.
Addendum: It appears that some improvements at Greenbelt Road and Hanover Parkway are underway. Not sure if that means improving bicycle access.
