I think those of us the regularly ride for trail might underestimate the number of people just riding up/down the road.
After climbing No Quarter early this morning I passed two guys coming down the road above the 6th.
On my way back up the road for lap two I saw another 5 ( three of these gravel bikes) coming down.
Sucks that after all these years it's cut off, but it is private property.
Go try and ride up from the top lot on Seymour to the top of the lifts, Parks is going to turn you back. Good luck also riding to the top of the lifts on Cypress via their summer maintenance roads.
Plenty of ways to get 1000m of vert in a ride between what is open on Fromme and quite streets around the Shore without fighting cars up Seymour or Cypress.
