I just spoke with a local cowboy there, Ken. He works for the Zion Ponderosa Resort. He was up on the road on horseback with his son this weekend hunting a mountain lion. He said the road is rutted but a go in a 4WD (said it might be possible in 2WD but didn't recommend it). He thinks we're crazy for wanting to kayak in there when the water is this high. I think he's crazy for chasing down a mtn. lion. To each his own. But it sounds like you should be able to get in there.
Every other outfitter and company in town just straight up said no it's not possible but had no actual info about the road. He was the only person I found with recent firsthand knowledge of the condition of the road. We're hopin' he's right and goin' for a thurs. put-in.
So if you happen to bump into Ken the cowboy, buy him a beer. And if there's some way you can throw some business towards Zion Ponderosa Resort, go for it. They were all very polite and helpful despite this having little (to nothing) to do with their business.
Good luck to everyone goin'. Maybe we'll see you on the river. And if anyone has anymore useful beta please throw it out there. This is the first time the four of us have done the narrows.
I was going to be vague but then I decided to do this other thing.
