Not being negitive, and not able to see the front of the pad very well in the pic... Edged concrete is slippery when wet, maybe brush the front edge of the tee pad and leave the sides smoothly edged.
I'll try to bring a crew from Salem if there is enough heads up for the next work party...
Also, Thanks for making more complicated courses... It forces us all to become better players.
Here are how I did the 5x10 tee pad forms for Keizer Rapids DGC this spring... pretty slick. http://youtu.be/PErKwK3o7Bc
