John Le Forestier said:[b]John, Fences don't make for very secure anchorage for a RR. If repairs need to be made to a wobbly fence the RR will be seriously impacted. Also since the fence must be shared with the neighbors you have no guarantee about how they will treat or modify it from their side.
Richard, that was a good post. How come no attachment to the fence, IYHO?
When I had a tract house my neighbor rented out his house for a time. The tenant hung chains on an already shaky fence and when a heavy windstorm hit the moving chains tore about 2 dozen boards off of it and almost knocked it down.
If I was to build along a fence line I not only would keep the RR separate I would provide at least a 2 foot (3 feet if possible) walk behind for fence maintenance. This would also allow access to the backside of the RR benchwork allowing for a greater width for scenery depth if practicable.[/b]
