Bob Thurston and I were loaned safety vests by the Army 10-Miler to wear while we verify the race day course layout. I liked it so much, I purchased one. It is a surveyor's vest with a zipper front and 4 handy pockets which I use for calculator, pen, cell phone, and notebook while measuring.It is available from Enviro Safety Products: OCCLUX Surveyor's Solid Two-Tone Safety Vest https://www.envirosafetyproduc...ty-vest-class-2.html.
To this vest, I attach an 81/2 x 11" sign: https://picasaweb.google.com/l...1kzo?feat=directlink .
I slip this sign into a plastic page protector, tape the open end, then attach it to the vest with safety pins. It survived a ride in heavy rain. It seems to help when measuring.
If you like the sign, feel free to print it: https://picasaweb.google.com/l...1kzo?feat=directlink .
