I have negotiated the bad section of road at PB in my fairly low-clearance
VW Jetta (last weekend, and 2 weekends before that).
It is getting bad, and it has to be looked at and then a path chosen
carefully, but it is negotiable in regular cars. I agree that it will get
worse.
I am willing to bring a shovel and help fix it, but we might want to get a
group to buy some gravel for that section.
