Bob,
We would be essentially throwing money away to improve an area before we are done working on it. We have graveled the road to the car barn, eliminating the mud that was there. Room for even more improvement? Yes. But, we are building the extension to the car barn, and I think the planned main entrance will be in the front, with an improved walk way and an easy walking surface. That would be the ideal spot to start, because we will be done work in that area.
I had planned to improve the walkway on the southside of the turn table this year after the electrical building was finished, but neither happened.
We are also planning a board walk across the front of the roundhouse that will lead you to the north side of the shop. That will be a huge improvement. This board walk will have to be rugged, because we all know someone will drive the tractor on it to get to the shop.. This is one that could be started, but can't be done until the roundhouse is..
