I rode Deer Creek and Pleasant Park road on Sunday and it was very nice. The repaving of Deer Creek is done and it's in great shape.
There was only one corner on Pleasant Park I had to check up because of the sand. A couple other corners had just a small amount of sand in the middle of the lane, but otherwise the road was in great shape.
Sounds like Lookout Mountain is quite heavily sanded, so Pleasant Park may be a better alternative. Keep it safe.
