I've used my vest twice now, and both were great experiences. I measured a 5K/10K in Vienna, Virginia and I've never seen people (including drivers!) act so politely and helpfully. Besides, folks seem to appreciate understanding what I am doing: "Oh now I get it", and other similar remarks. A woman asked me if I was the person whose initials were on all the course maps-- she felt like she met a celebrity. (I am still hoping she will get in touch and learn to measure courses.)
I was also asked to monitor a course I had measured for the USATF 12K in Alexandria. For that one I printed out "MONITOR" and taped that word over "Measurement". I guess I didn't want runners to think the course was just now being measured!
I will try to share some pictures:

If that doesn't work I'm sure I'll hear about it!
A few comments: the sign was attached to the back of the vest with little brass fasteners. Since then I've replaced those with wire twist-ties designed for closing plastic bags, and I think that's a little more durable. Still I don't think it's a great idea to wear the vest while driving your car, seems like that's just asking for something to get loose or crushed, etc. Something else to think about: since the vest doesn't have pockets you still need somewhere to put stuff like calculator, notebook, map, unless you mount all of that on your handlebars. So I'm still using my vest from the 1980's which by now sports a high proportion of duct tape!
I wish everyone safe riding in the new year!
