I meant on the blinds but it's still good to make it 2nd nature. Not on the opposite edge (gravel city) but on an imaginary line a couple feet from the yellow to give a cushion.
I was riding last week up to Evergreen from Morrison on the twistys (lots of blinds, makes you think your riding in a circle they are so long) and sure enough a stupid cager comes whipping around in my lane. Damn glad I wasn't on the yellow or I would have hit the slacker.
Gravel sucks but head on impact is always worse.
Just my opinion

Ride safe.
