Obstacles in the works.

I went to the r/c field and marked out a circle. It ended up real close to the first spot. The gravel and pipe are 10 feet inside the circle. The pipe can't be pulled out. I went back to the field after supper and found the club president and others shooting the breeze, just like old times. I found that the gravel is part of test holes dug to check the ground for construction. The pipe is a mystery but may be to warn the farmer of the gravel pile hidden in the grass. I plan to go there again soon and dig around the pipe to loosen it and make it removable and see what I can do from there.
