Ah! State Route 49 is indeed another name for the infamous Jungo Road. I had to zoom way in on Google Maps to be sure.
Indeed, Yurtgirl, skip it. It's unlit, unpaved, rocky, and not constantly traveled. I believe it's technically
shorter, when you're just looking at a map, but the speed at which you would have to go to avoid catastrophe erases any gains you would make. If you break down on it, you may not immediately be assisted. And it's overrun by kamikaze rabbits (we may have hit up to 3 of 136 who specifically tried to die under our wheels. Quoth Leslie: "There go the Johnsons!")
A friend and I innocently & stupidly took that road 10 years ago, and since we escaped injury, it's a funny story, but I could never recommend it.
(There's a fella on these boards who's going to try it via pedal power, but he's very much doing so on purpose just to see if he can, and people are lining up to shake his hand if he makes it.)
