I hear you, it will be hard to close it off in such a manor that people don't try to bypass it. But people already drive up the hill when they can't do WW instead of taking a minute to drive down and around, so not making WW the gatekeeper is not going to save the hillside....I'm not sure why I'm hesitant about making WW the entrance--partly because it originally wasn't the entrance, partly because I know people will terrorize that hillside, and partly because when that obstacle is wet, very few rigs can get up it. Could crawl any line imaginable in my old rig when it was dry--but in the rain I couldnt get up it to save my life.....
That's the very idea, if you can't drive WW wet, you can't drive Con wet. Radiator rapids is polished to the point that you can't stand on it when it's wet, let alone drive it. WW is by far easier to drive wet than the rapids are now....I can just see someone go up there and there is a puddle at the bottom or it's raining and they can't get up it but they know they could do the rest of the trail so they blast up the gully and go around......that would be bad...
