Let’s see…
Todd: I’m kinda with you on using different radii and going for wide, although I did have my heart set on having that passing siding where it currently is. Still, having a wider curve is tempting. No problem with frost heave. We’re in a coastal climate so until the Pacific freezes over (Hey, it could happen. I’ve seen them doomsday films), there’ll be no heaving. Of course we got earthquakes…I’m not doing trenches. As it is, I’m not keen on dragging in only a couple of hundred pounds of DG in bags. Maybe stakes will work, although I looked at some Hardiboard I saw being installed and it looked tempting, even though a well-known member of our community said it was crap. No worries about overhanging anything.
Jerry: don’t even mention “fence,” as it sends DW into a budget tizzy. The fence we have prolly needs to be replaced, mostly because the 12 x 12 posts, which are set in concrete and in the ground, are being termited to death. So are some of the baseboards, which is what you see in the photo. Critters have dug openings in them, hence the little bricks, which are also holding up the baseboard. I’m thinking of getting some Trex and putting that in place. Then let them buggers try ta chew through that!
Ralph: In the photo the track appears close to the retaining wall (actually, it’s the planter wall), but that’s just 'cause I was messing around. I’m keenly aware of clearance. And Clarence, whoever he may be.
