jimw67: my original idea of this location was to place a nice size stick to the side of the trail and add a bison tube in the en d. This was taken twice so kids apparently like to play with sticks. Then I cahnged this to just a bison tube beside (at the edge of the concrete blocks). The concrete blocks get moved by the city every once in a while which crushes or covers the bison tubes. So I have decided to give up on this location. The first archive for me. Jim
