This is bringing back some memories - I haven't ridden the F3 for a few years but I suspect the widened sections will now be more dangerous than before. If you do ride the F3 beware of truck tyre delaminations.
Driving down F3 to work at WyoNg week before last, passing a concrete pump truck and one of it's inside rear tyres blows. Heart rate spiked like it does on Blood Hill...glad I was not on m bike.
