When I saw this set of markers pop up I thought "could there be such a thing so easily accessible" and today was my day to find out. Parked and walked through the empty park and once I started to get a little closer, it was plainly obvious where these markers were located. At least that part was easy for the day. When I approached this one I noticed that there was a bag at the base and some equipment attached to the top. Noice, finding a maker and it was actually being used. Snapped and then moved on to the next.
