I went out a couple of weeks ago with hotpoint in his spiffy new Civic Si and we laid out about half the rally, and also smacked his car into a rock and had a pretty long day exploring roads to figure out some of where the rest of the rally would go. Last weekend I went out and did the rest of it, which went much more smoothly since we'd done the prep work already.
I'd been shooting for a total length of 100 miles and a first car finish at 5 PM. After putting all the bits together in the computer and doing the preliminary mileages and timing, it looks like I've got 99.3 miles and first car finish at 4:59.61. There's still some work to do -- mileaging and checking -- and I'll have to drive the course two more times before it's finished. But it's coming along nicely.
