I'd have to toss my bike over a barbed wire fence, or maybe cut the lock. The service road winds between a bunch of natural gas storage tanks so I don't think they'd willingly let me in. There's a "≠" symbol where the service road is fenced off, which I assume means impassible but "≠" isn't on the map legend so I'm not sure. When I hit the cycle layer, the ≠ symbol goes away
